Perfect

Saloma Hammond is not your typical 12 year old.

Sal counts her steps between classes, wears a school uniform that isn't required, and prefers to stay locked inside her tightly controlled OCD world. But when the lure of the perfect snowflake entices her to join the Weather Club, her anti-social shell begins to crack. At the same time, dozens of phones have gone missing, and her classmates are getting suspicious.
If Sal can unlock her pattern-driven mind to identify the workings of the real thief and then set an irresistible trap at the Science Fair, she may just learn how powerful friendship can be.
