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 boyfriend-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.
Siena Bernstein is leaving her yoga mat behind for a semester of study abroad in Munich. She's thrilled with the prospect of a German adventure (her horoscope is encouraging as well), but she hopes to make more than just her dreams come true while she's there. Siena's dad, who passed away when she was a baby, kept a "Carpe Diem" list-sort of his top-ten adventurous things to do. He completed all but one of the tasks-going to Germany to thank the man who helped smuggle his family past the Berlin Wall. Amidst her adventures in biergartens, Alpine skiing, and a rigorous course load, Siena is on a quest to complete her father's list. But she's also set on having the best possible time while she tries. With the help of two new best buds and a handsome RA in her dorm, she'll surely succeed.
