" Do you remember infinity?”
Slowly, I turned around. “What about it?”
Tossing something toward me, he said, “Catch.”
I reached out and caught it in the air. A silver necklace. I held it up and examined it. The infinity necklace.
It didn’t shine the way it used to; it looked a bit coppery now. But I recognized it. Of course I recognized it.
“What is this?” I asked.
“You know what it is,” he said.
I shrugged. “Nope, sorry.”
I could see that he was both hurt and angry. “Okay, then. You don’t remember it. I’ll remind you. I bought
you that necklace for your birthday.”
My birthday.
It had to have been for my sixteenth birthday. It was the only year he ever forgot to buy me a birthday
present—the last summer we’d all been together at the beach house, when Susannah was still alive. "
