It seemed so logical at first. Fourteen-year-old Lenny Cyrus had loved Zooey Andrews since third grade. All the boy genius needed to do to win her heart, surely, was shrink down to the size of an amoeba, ooze into a gelatin capsule, and have his friend Harlan slip it (him!) into Zooeys Diet Coke. Told in three voices, this fantastical middle grade novel takes Lenny deep into Zooeys loud, splashing innards, where a talking astrovirus named Astro has a bad attitude about white blood cells (self-righteous pus-bags) and aromatic hormones disco dance. The question is, will Lenny and Zooey survive his crazy experiment in nanotechnology?
