Einstein P. Fleet is forced to attend camp in the desert despite his best arguments, and man-eating spiders are the least of his problems. The camp is haunted, the campers are turning into monsters, and his counselors are aliens plotting to sell the kids to an intergalactic zoo (once they completely transform into mummies, vampires, and werewolves). He writes home and relays his predicament, but his parents dont believe a word of iteven though its entirely true.

Einstein may have been able to uncover government plots and survive seventh grade, but will he be able to save himself and his fellow campers from a terrifying fate?
