1 ill-fated hot dog costume. 2 ex-best friends. And 11 days to seduce a guy.

Avery James doesn't believe in romance. She is quite savvy in biology and understands that love is just hormones and chemical compounds. She also has a lot of practical plans in mind: saving enough money for a humanitarian program in Costa Rica before the summer. But when the manager of the Digitity Booth where Avery works denies her a raise, Avery tries to find $500 for the trip of a lifetime on her own and accepts an unexpected offer. Deal? Avery must steal her nemesis Hannah's boyfriend before graduation. The girl has only 11 days to seduce Zach Greeley.

Avery is confident that she will easily cope with the task. But a series of midnight stand-up shows and impromptu dance parties (not to mention one particularly intimate get-together at a car wash) force Avery to reconsider his views on love. Is it all about Zach's signature cherry lemon Slurpee or has Avery truly started to fall in love with him? Can the girl steal Zach from Hannah before Zach steals her heart?
