The Clique Summer Collection #4:Kristen by Lisi Harrison

Kristen sets sail on the Love Boat... With the rest of the Pretty Committee scattered across the globe, Kristen is stuck in summer school at OCD, making good on her scholarship commitments. No sleepover horse camp, no Hawaiian spa, no Spanish vacation, not even a trip to Orlando.

It looks like Kristin is about to ride the wave of first love. . . .
