Gertie’s Leap to Greatness by Kate Beasley

Gertie Reece Foy is 100% Not-From-Concentrate awesome. She has a daddy who works on an oil rig, a great-aunt who always finds the lowest prices at the Piggly Wiggly, and two loyal best friends. So when her absent mother decides to move away from their small town, Gertie sets out on her greatest mission yet: becoming the best fifth grader in the universe to show her mother exactly what she’ll be leaving behind. There’s just one problem: Seat-stealing new girl Mary Sue Spivey wants to be the best fifth grader, too. And there is simply not enough room at the top for the two of them.
