The Trials and Tribulations of First Love

Lillian (Lilla, for short) Watanabe is everyone's dream daughter.
Ranked second in her class, class president, and...
has never had a boyfriend.
Or a kiss.
Or been in love.
Quite the contrary, actually--- the strongest relationship she's had with a guy is with her next-door-neighbor, Elias Barlowe, and that's a relationship forged of hatred and distaste.
Until the summer before senior year, when Lilla's mother hires Elias to help with landscaping, throwing off her beginning of summer party Lilla will take any measures to hide from her parents. Elias, in a bet with his friends that he can get Lilla to agree to date him by the end of his summer, issues an ultimatum to Lilla, and the two reach a deal:
Lilla will pretend to date Elias, and Elias will pretend the booze-soaked debauchery of the first night of summer never happened.
But as the two enemies catch feelings, it's hard to stop the ball from rolling:
Such are the trials and tribulations of first love.
