Seventh grader Lennie Miller has a gift. Her new hometown of Bailey, Indiana, sits on the edge of the Mystical Realm, and she can see the creatures that cross over from that world to ours. The creatures know that Lennie is a Pattern Finder, and they come to her for help with their math problems—and they have a lot of problems. With her best friend Gil, Lennie solves an array of ghastly and ghostly dilemmas. She computes a ghost girl's inheritance, determines the winner of a Bigfoot foot-size contest, calculates how much money a vampire and a werewolf need to spend on a ring for the girl they both love, and helps a monster chef with his recipes.
All of these problems are scattered among the biggest problem of all: Lennie must save the Mystical Realm from a horde of brain-eating zombies. Can she figure out how to stop them in the Mystical Realm before they reach Bailey?
Night of the Frightening Fractions is the second volume in the Mathematical Nights series. The book contains several real-world (other-world?) math problems, which readers can try to solve on their own, or they can follow along as Lennie and Gil calculate the solutions.
