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 reading Oliver’s private and vulnerable messages for months. But Ben, an astronomy student in Seattle, won’t remain a stranger for long.

When they finally meet in person, their spark is undeniable. Everything seems perfect until Oliver discovers something strange that could keep them from being together.
