SASS - Up Over Down Under by Micol Ostow

Eliza Ritter has high expectations for her semester in Melbourne, Australia. Sure, she's participating in an environmental program, but really she hopes to spend her time meeting cute boys. So when she meets a hot surfer, she is thrilled! 

Aussie Billie Echols, on the other hand, actually does have an interest in the environmental program she's signed up for in Washington, D.C. But the States are nothing like she expected, and soon Billie is caught in the middle of an unexpected controversy. 

This novel offers romance in the land down under - and right here in the U.S. - when two exchange students swap places!
