Chapter 1

Chapter 1: The Phone Call

The call came at 3:47 in the morning, that hour when nothing good ever happens. Lauren had been dreaming about something mundane—grocery lists, maybe, or traffic—when her phone lit up the darkness of her bedroom.

She fumbled for it, squinting at the screen. Tom's name glowed there, and for a moment she felt only annoyance. Her younger brother rarely called, and when he did, it was usually because he needed something. Money for a business venture. A place to crash between apartments. Someone to listen to his latest grand plan.

But Tom never called at 3:47 in the morning.

"Lauren." His voice cracked on her name, and she sat up in bed, suddenly wide awake. "It's Mom."

The next few hours existed in fragments. Lauren threw clothes into a bag while her husband David asked questions she couldn't answer. The drive from Boston to the small Connecticut town where she'd grown up took three hours, but she remembered almost nothing of it except the gray light of dawn spreading across the highway and the way her hands wouldn't stop shaking on the steering wheel.

Margaret Chen had been sixty-three years old and in perfect health, or so they'd all believed. She'd gone to bed Tuesday night after watching her favorite cooking show and simply never woke up. A massive stroke, the doctors said. Painless. Quick. As if that was supposed to be a comfort.

Tom was waiting on the front porch of their childhood home when Lauren pulled into the driveway. He looked smaller than she remembered, though he was thirty-one now and had their father's broad shoulders. But grief had a way of shrinking people, she thought, and Tom had always been closer to their mother.

"Dad's inside," Tom said as she climbed the porch steps. "He's not—" He stopped, shook his head. "He's not doing well."

Lauren hugged her brother, feeling the unfamiliar angles of his body against hers. When had they stopped hugging? When had she stopped really seeing him? They'd grown apart in the way that siblings often did, their lives diverging after college into separate cities, separate careers, separate concerns. She was a financial analyst in Boston with a husband and a mortgage and a carefully planned life. Tom was a freelance photographer who'd never stayed in one place longer than a year, who'd borrowed money from their parents more times than Lauren could count, who'd always been the golden child despite—or maybe because of—his lack of direction.

Their father, Richard, was sitting in his armchair in the living room, staring at the blank television screen. He didn't look up when Lauren came in.

"Dad." She knelt beside him, taking his weathered hand in hers. "I'm here."

Richard Chen had always been a quiet man, steady and reliable in the way that some men of his generation were. He'd worked as an engineer for forty years, had provided for his family without complaint, had loved his wife with a devotion that Lauren had always admired even when she didn't fully understand it. Now he looked hollowed out, as if someone had scooped away everything that made him who he was.

"She was fine," he said, his voice barely above a whisper. "She was fine yesterday. We had dinner. She laughed at something on television." He looked at Lauren then, his eyes red-rimmed and bewildered. "How can she be gone?"

Lauren had no answer. She stayed kneeling there, holding her father's hand, while Tom made phone calls in the kitchen and the morning sun crept across the worn carpet of the room where she'd taken her first steps.

The funeral was four days later, a blur of casseroles and condolences and relatives Lauren barely recognized. Margaret had been well-loved in the community—she'd volunteered at the library, had organized the neighborhood watch, had baked cookies for every new family that moved onto their street. The church was full, and afterward, the house was even fuller, packed with people sharing memories of a woman who had apparently touched more lives than Lauren had ever realized.

She moved through it all in a daze, accepting hugs, murmuring thank-yous, making sure her father ate something and that Tom didn't disappear into the backyard with his camera the way he did when things got too overwhelming. She was the older sister, the responsible one. This was her role.

It wasn't until three days after the funeral, when the last casserole dish had been returned and the last sympathy card had been opened, that Lauren found herself alone in her mother's bedroom.

She'd been putting it off, this task. Someone had to go through Margaret's things, to sort and organize and decide what to keep and what to donate. Tom couldn't do it—he'd barely been able to look at their mother's photograph without crying. Their father certainly couldn't. So it fell to Lauren, as things often did.

The bedroom looked exactly as it always had: the floral bedspread that Margaret had loved, the collection of ceramic birds on the dresser, the stack of romance novels on the nightstand. Lauren sat on the edge of the bed and breathed in the faint scent of her mother's perfume, something light and floral that she'd worn for as long as Lauren could remember.

"Okay, Mom," she said to the empty room. "Let's do this."

She started with the closet, sorting clothes into piles: keep, donate, undecided. Her mother's style had been practical—cardigans and slacks, sensible shoes, the occasional bright scarf for color. Lauren found herself crying over a green sweater that she remembered from a dozen holiday dinners, and she allowed herself that, sitting on the closet floor with the sweater pressed to her face until the tears stopped.

The dresser was easier. Jewelry that would go to Lauren and any future daughters she might have. A collection of handkerchiefs that seemed too personal to give away. Photographs tucked into the mirror frame—Lauren and Tom as children, Lauren's wedding day, Tom at his college graduation.

It was in the bottom drawer, beneath a stack of old scarves, that Lauren found the box.

It was small, wooden, with a tarnished brass clasp. Lauren didn't recognize it, which seemed strange. She thought she knew all of her mother's things, all the treasures and trinkets that had filled this house. But this box was unfamiliar, and when she lifted it, something shifted inside.

She carried it to the bed and sat down, turning it over in her hands. There was no lock, just the simple clasp, and when she opened it, she found a collection of letters tied with a faded blue ribbon.

Love letters, she thought at first. From Dad, maybe, from when they were young. She smiled at the thought, imagining her practical father composing romantic missives, and she untied the ribbon, curious to see this hidden side of her parents' relationship.

The first letter was dated August 1992. Lauren would have been eight years old that summer. Tom would have been—

She stopped. Read the first line again. Then the second.

My darling Margaret, I cannot stop thinking about our time together...

The handwriting was not her father's.

Lauren's hands began to shake. She told herself to stop reading, to put the letters back in the box and the box back in the drawer and pretend she'd never found them. But her eyes kept moving across the page, taking in words that rearranged everything she thought she knew about her mother, her family, her life.

The man's name was James. He'd met Margaret at a conference in Hartford—she'd been volunteering at the registration desk, and he'd been a keynote speaker. He was married too, with children of his own in California. Their affair had lasted almost a year, a secret carved out of business trips and lies and stolen afternoons in hotel rooms.

Lauren read through the letters with growing horror, watching the relationship unfold and then, inevitably, end. James's wife had found out. He was ending things, going back to his family, asking Margaret to forgive him for what he couldn't give her.

The last letter in the stack was different from the others. It was from Margaret to James, never sent. The paper was tear-stained and wrinkled, as if it had been crumpled up and then smoothed out again.

I'm pregnant, Margaret had written. The baby is yours. I know this because Richard and I haven't been together in months—things have been difficult between us, and I thought that was why I turned to you. But now I understand that I was looking for something he could never give me, and I found it, and I have to live with the consequences.

I'm not going to tell you. I'm not going to tell anyone. Richard and I will reconcile—we already have, in fact. He's been so gentle with me lately, so patient. He'll believe the baby is his. He'll love this child, I know he will. And I will spend the rest of my life making sure that no one ever knows the truth.

I loved you, James. Part of me always will. But I love my family more, and I choose them. I choose the life I've built, imperfect as it is. I choose to be the mother my children need, even if it means carrying this secret forever.

Goodbye.

Lauren read the letter three times. Then she counted backward from August 1992, and the math confirmed what she already knew.

Tom had been born in April 1993.

Tom was not her father's son.
