Twins Aidan and Olivia live in a desolate house on the edge of a dirty, swampy lake. School is out for the summer and with no other kids around, the twins crave some excitement, so they convince their parents to let them camp out by the lakeshore one spooky night under a full moon. Aidan loves to scare his sister and has plenty of funny tricks up his sleeve to creep her out during the campout. But little does he know, Olivia has unwittingly unleashed a swamp monster, courtesy of the Scaremaster, and so the scares that happen during their camp out won't be pretend... and they won't be funny! Can Aidan and Olivia outrace and outsmart the monster and the Scaremaster?

For fans of Goosebumps, Eerie Elementary, and the Haunted Library series, B.A. Frade brings frightfully funny tales to life in this thrilling new series.
