Tess, who has always loved math, uses mathematical concepts as a tool to help solve two complicated mysteries involving her secret crush Richard and her mother's co-worker. Reprint.
Tess has always loved math, and she uses mathematical concepts to help her understand things in her life, so she is dismayed to find out how much math--and life--can change in eighth grade.
Tess loves math because it's the one subject she can trust—there's always just one right answer, and it never changes. But then she starts algebra and is introduced to those pesky and mysterious variables, which seem to be everywhere in eighth grade. When even your friends and parents can be variables, how in the world do you find out the right answers to the really important questions, like what to do about a boy you like or whom to tell when someone's done something really bad?
Will Tess's life ever stop changing long enough for her to figure it all out?
