Newly minted professor Evangeline "Van" Thompson's academic dreams have turned into nightmares. She can't wait to escape the pressure cooker of the university to spend the summer at Camp Firefly Falls with her bestie, Nate.

Van has fond memories of the blonde moppet, but when Willa shows up at camp, she's not so little anymore. She's grown into a bombshell and a menace on the tennis court—why do those skirts have to be so short, anyway?

Willa Carter has had a crush on Van Thompson since the third grade but Van's always been more interested in hanging out with Willa's older brother. Not much seems to have changed—Van's managing the camp's web presence while Willa rocks her tennis whites.
