Cat Wilcox has left chilly Boston for sunny Mexico and a summer of girl bonding with her best friend, Sabrina. But Sabrina has a surprise. She is accompanied by her boyfriendโa boyfriend Cat didnโt even know existed. So rather than Sabrina and Cat spending their study-abroad semester working together at the orphan school building site, Cat expects sheโll be hammering nails all by her lonesome. Then she meets Aidan. Heโs cute, heโs smart, and heโs paying her a lot of attention. Cat canโt tell if heโs flirting or friendly, but sheโs not sure it matters. Isnโt it easier to be just friends? But this is enchanted Mexico and, between hiking in the rain forest, diving off waterfalls, and finishing the orphan center, itโs going to take a little bit of salsa spirit, and a lot of heart, for Cat to make it through the summer unchanged.
