My wife finally gave birth to the daughter we'd begged for after six miscarriages — then at her 18th birthday party, the girl I raised shoved a hidden certificate against my chest and asked how I could have let her mother do this.

Callie came down forty minutes later. She had the letter open in both hands, like folding it back up was more than she could do just then.

She sat down across from Erin. I stayed by the counter.

"She knew she might not make it," Callie said.

Erin nodded.

"She wrote about you. She said you were the only person on earth she trusted. She said if anything went wrong, she knew you'd handle it." Callie looked down at the page. "She wrote — 'Erin will know what to do. She always does. Tell her not to carry it by herself.'"

A sound came out of Erin that she couldn't stop.

"She knew you'd carry it by yourself anyway," Callie said. "She wrote it down. She knew exactly who you were."

"She knew me better than I've ever known myself," Erin said.

Callie laid the letter flat on the table between them.

"She described me," she said. "What she hoped I'd turn out like. She said she wanted me to have her stubbornness and your patience." A pause. "She said she hoped I'd find someone who loved me the way Dad loves you."

I had to turn and look out the window.

"She sounds like somebody I would have liked," Callie said.

"You would have loved her," Erin said. "And she would have driven you completely out of your mind, and you'd have loved her through every second of it."

Something crossed Callie's face. Not a smile. Something thinner and more breakable than a smile.

"I'm angry," Callie said. "I need you both to hear that clearly. I'm not finished being angry."

"I know," Erin said.

"You took something from me. You and Grandma Joan both. You sat in a room and decided how much of my own life I was allowed to have."

"Yes," Erin said. "We did. There's no version where that isn't true."

"And I don't know how long it's going to take before I can look at you and not think about it."

"I'm not asking you to rush."

Callie folded the letter, slow and careful, along its old creases.

"But I also know," she said, and stopped, and started over. "I know you drove four hours in the middle of the night to be with her. I know you carried me out of that hospital. I know you sat up with me every time I ran a fever, and you showed up to every game and every recital and every stupid science fair, and you never once — not one time — made me feel like I was anything other than yours."

Erin didn't speak.

"So I'm holding both of those things at the same time right now," Callie said. "And they're heavy, and they don't cancel out, and I need you to stop expecting them to."

"I understand," Erin said.

Callie looked over at me. "And you. You kissed my forehead in that hospital room before you knew a single thing. Before anybody gave you a reason to."

"You were mine," I said. "I knew it the second I walked through that door."

Callie pressed her lips together, hard.

"Okay," she said finally.

It wasn't forgiveness. It was a door left standing open instead of slammed and bolted.

She stood up. "I'm going back outside. It's still my birthday, and there are people in our backyard who got in their cars and drove here for me." She picked up the letter. "But tonight, after every last one of them goes home, the three of us are going to sit down and you're going to tell me everything. Start to finish. Every detail you've got."

"We'll tell you all of it," I said.

She walked to the back door and stopped with her hand on the frame.

"That woman," she said to Erin. "Dennis Kroll's daughter."

"Yes?"

"What's her name?"

"Nadia," Erin said. "Nadia Kroll."

Callie nodded slowly.
