I’ve missed you every day since you left. But I’m sure you already knew that. It’s time to let you go now. I’ll miss you all the time, Sam.

It’s been a year since his best friend, Sam, died. Even though Oliver knows he won’t get a response, he can’t stop texting Sam’s number, especially as the anniversary of his death approaches.

Then one day he accidentally hits the call button, and someone picks up.

The voice on the other end isn’t Sam. Sam’s number was reassigned and a stranger has been receiving Oliver’s private and vulnerable messages for months. But Ben, a college student in Seattle, won’t remain a stranger for long. Oliver knows he should stop communicating now that he knows the truth—but he can’t get Ben out of his head.
