The Secret Spiral — Gillian Neimark

It's just another boring Wednesday in May for ten-year-old Flor Bernoulli of Brooklyn, New York. As soon as school is out she hurries to the popular Sky High Pie Shop down the block, owned by the wonderfully mysterious Dr. Pi. But when she gets there, her life changes forever. Dr. Pi reveals he is actually an ancient wizard, in charge of a very special cosmic fire that keeps nature in balance. Without him, every single thing that has the shape of a spiral -- from seashells to galaxies to the inside of your ear -- will cease to exist. Flor wonders if Dr. Pi has lost his mind, but then two tall blond strangers from another planet show up, hoping to steal Dr. Pi's fire for themselves. The adventure of a lifetime has begun. As she travels in time and travels in space, Flor learns that only she has the magic to help Dr. Pi protect the fire, save the spiral, and keep the world spinning just as it should.
