Demigod Wizards Book 1: Set in Stone

Demigods Nico di Angelo and Will Solace have just returned from their adventure in Tartarus when they, Percy, Thalia, and Annabeth are called upon on another quest in another world: one filled with magic, wonder, strange sticks, and an arrogant wizard named Harry Potter.
The demigods are sent to Hogwarts to protect Harry, for he is destined to take down the Dark Lord. However, things get complicated pretty quickly, and it becomes even more complicated when it is discovered that two of the demigods are related to Voldemort, the most evil wizard to have lived. Can the demigods get past these differences and gain the chosen one's trust, all while protecting him from what lies in the Chamber of Secrets?

Contains spoilers for Percy Jackson and the Olympians, Heroes of Olympus, Trials of Apollo, The Sun and the Star, and Harry Potter and the Chamber of Secrets
