Evolution, Me and Other Freaks of Nature, Robin Brande

Mena's first year of high school is turning out to be miserable. Her former friends hate her, her parents barely tolerate her, and she isn't even welcome in her church anymore. (It's complicated, but basically she apologized to someone and he's using her letter of apology to sue a bunch of people for harassment.) Things start to get interesting in science class when her lab partner turns out to be a cute nerdy type and her former friends protest the unit on evolution. I couldn't put this one down! Sweet romance and some weighty issues.
