Leah Grayson has lived in Siren Cove all her life. It's where she buried a time capsule with her fifth-grade class. Where she spent an unforgettable night on the beach with her first love. Where she married then divorced her rotten ex. But there's something ugly going on in her pretty little town. When Leah organizes a reunion for her fifth-grade classmates to open their time capsule, they discover a roll of film no one remembers saving. Afterward, strange incidents begin happening. Warnings. Accidents. Random acts of vandalism. Luckily, her first love is back in town, too. Ryan Alexander has made it big with a wildly popular social media startup, but he's still the same sweet, cynical man she fell for all those years ago. And the chemistry they felt as teenagers is as strong as ever. A nostalgic fling turns deadly when someone is convinced Leah has the key to secrets long buried. With no way to know whom they can trust, Leah and Ryan will have to seek out the answers themselves...
