Heart and Salsa: S.A.S.S. (Students Across the Seven Seas), Book 6

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 boyfriendamp;mdash;a boyfriend Cat didn't even know existed. So rather than Sabrina and Cat spending their study-abroad semester working together at the orphan school building site, Cat expects she'll be hammering nails all by her lonesome. Then she meets Aidan. He's cute, he's smart, and he's paying her a lot of attention. Cat can't tell if he's flirting or friendly, but she's not sure it matters. Isn't 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, it's going to take a little bit of salsa spirit, and a lot of heart, for Cat to make it through the summer unchanged.
