Seventeen-year-old Ivy Living is on top of the world. As the founder of Horizon Harborers, she is revered as a pioneer in the social movement sector, and her organization’s eye-catching gadget-assisted “missions”, coupled with her bubbly personality and endless supply of charm, have garnered enough attention worldwide to turn her into an international sensation. Her junior year at the highly exclusive Alden Hall begins as all previous years have, with Ivy balancing school work, her duties at Horizon Harborers, and the trials and tribulations of being popular and famous, with the grace of a prima ballerina. That is, until one of her study dates is crashed by a homemade metallic beast trying to kill her.
Narrowly avoiding a gruesome death, Ivy is thrown headfirst into the investigation of a lifetime. 
To find her would-be killer, Ivy must partner with Victor Garza, her academic rival and the one person who seems stubbornly resistant to her charms. Victor is infuriating, a cynic, and definitely more than a little skeptic of Ivy’s organization and the morality behind it all. Unfortunately, he is also the only person she knows with the investigative and technological skills to find whoever is behind the attack.
As the two conduct their investigation, they must put their differences aside and let go of their preconceived notions to find the truth buried deep beneath the surface. The more time she spends with Victor — and starts catching feelings for him — the more Ivy is forced to question the beliefs she founded Horizon Harborers on. Could an organization that sprouted from hope and goodwill have curdled into something sinister? Was it ever any good at all? Ivy’s search for answers will yield plenty, perhaps more than she  bargained for.
Set in the fictional city of Seaside, Massachusetts, POWER HIGH combines the action of the Gallagher Girl series by Ally Carter and the rivals-to-lovers romance of Check And Mate by Ali Hazelwood, all while being an homage to 2000s TV shows such as Kim Possible and Totally Spies! It explores the phenomenon of “voluntourism” and proposes an answer to the question: What does it really take to change the world for the better? And who gets to decide what that means?
