The Color of Milk by Torun Lian

6.06

Selma's mother died giving birth to her, and Selma's step aunt is living proof that men only cause trouble. So the 11 year old girl makes a deal with her best friends that they will stay away from boys and dedicate their lives to science. And by the way, Selma was probably born on another planet and not meant to fall in love with anyone. But what happens when her friends break the pact, and she actually meets a boy who's not like the rest?
