It's Not Summer Without You (Summer, #2)

An alternate cover edition for this ISBN can be found here.Last year, all of Belly’s dreams came true and the thought of missing a summer in Cousins Beach was inconceivable. But like the rise and fall of the ocean tide, things can change-- just like that.

Suddenly the time she's always looked forward to most is something she dreads. And when Jeremiah calls to say Conrad has disappeared, Belly must decide how she will spend this summer: chasing after the boy she loves, or finally letting him go.
