This junior novelization retells storylines from many episodes of the hit new show Mysticons! In Drake City, where magic and technology meet, four girls are brought together by an ancient prophecy. Princess Arkayna, her friend Em, and street kids Zarya and Piper are transformed into the Mysticons—heroes with incredible magic powers. But to unlock their full abilities—and save Arkayna's parents, the queen and king—the Mysticons must find the Codex. An ancient spellbook with the power to fight evil, the Codex was split into four pieces, each hidden away with riddles and puzzles as the only clues. The Mysticons must hurry; forces of evil want the Codex themselves—and they'll be able to use its powers to destroy Drake City and anyone who would stop them. Based on the animated television series, Mysticons: Quest for the Codex includes an 8-page color insert with artwork from the show! Mysticons characters, designs, and elements © 2018 Nelvana Limited.

Lonely and overprotected, Wesley soon finds himself on a fantastic adventure.
