Belly Conklin has loved Conrad Fisher for as long as anyone can remember. The problem? Conrad Fisher has never been looking at Belly. He’s been looking at her sister. Delilah Conklin has spent every summer loving Conrad in silence—burying it deep enough that even she almost believed it wasn’t there. But when one summer changes everything, stolen glances become lingering touches, friendship becomes something dangerous, and the line between loyalty and love begins to blur. At Cousins Beach, hearts break quietly. And sometimes— the person you were never supposed to love ends up being the one who chooses you.
