Frenemy of the People

Clarissa and Lexie couldn't be more different. Clarissa is a chirpy, optimistic do-gooder and a top rider on the school's equestrian team. Lexie is an angry, punk rock activist and the only out lesbian at their school.
When Clarissa declares she's bi and starts a Gay-Straight Alliance, she unwittingly presses all of Lexie's buttons, so Lexie makes it her job to cut Clarissa down to size. But Lexie goes too far and finds herself an unwitting participant in Clarissa's latest crusade. Both are surprised to find their mutual loathing turning to love.
A change in her family's fortunes begins to unravel Clarissa's seemingly perfect life, and the girls' fledgling love is put to the test. Clarissa and Lexie each have what the other needs to save their relationship and the people they love from forces that could tear them all apart.
