Told from the perspective of three seemingly unconnected teenagers, Called Upon steers the adolescent reader through a series of twists and turns that merge together with jaw-dropping results. Kaitlin, the social pariah of her high school, is so relieved to have made friends at Camp Overlook that she is willing to look past the camp's anomalies: creepy counselors, 24-hour video surveillance, and campers disappearing quietly into the night. Dr. Forsythe, the mastermind behind the Overlook experiment, explains that Kaitlin has a genetic gift--one which laid dormant until her stay at summer camp. Having never considered herself normal, let alone special, Kaitlin is dazzled to have an ability with world-changing implications. After a terrifying warning from Dr. Forsythe's embittered son and then discovering a dead body in the doctor's walk-in freezer, Kaitlin must decide whether to embrace her new gift and follow Dr. Forsythe or use her gift to defeat the very system from which it was created. By the end, readers come away from Called Upon feeling surprised and exhilarated, they will also, like Kaitlin, leave with a new understanding of their own intrinsic worth and limitless potential.
