The group is on their knees in front of Negan, thinking it was all over. As the leather jacket-wearing man is pointing is barbed wire bat at people, choosing who he is going to kill, someone interrupts everything. Little did the survivors know, this person would change their lives, for better and for worse.

Hallie Johnson is a lifeguard at Palm Rose Beach, and she is in a very complicated situation. It's the summer before she goes off to college, and she's faced with the one who got away and the one she never really recovered from, and both of them broke her heart. And now they both want her back. It will be a summer of misunderstanding, forgiveness, life-guarding of course, big decisions, maturity, and just maybe, a little bit of love.
