Gr 5-8 When the Demons from Demonside, led by the fearsome Demon King, start pouring through a newly opened dimensional portal, only one warrior is brave, strong, and powerful enough to stop them: Great Warrior! Unfortunately, she already has plans for the day. Can Great Warrior be persuaded by her friends to act in time? And will Great Warrior even have friends when everyone finds out the terrible secret she's been hiding? Thankfully, those in need can always count on Great Warrior, especially if there are snacks involved. Flores and Gunn bring this small but powerful hero to life in this work that's based on the popular webcomic. The art is clean and colorful and ideal for the tone, which is similar to the TV show Adventure Time but a bit more accessible. The book also carries the same message about friendship and self-esteem. VERDICT This worthy addition will appeal to middle school readers looking for high-energy excitement, interesting characters, and a cool female protagonist. Erik Knapp, Davis Library, Plano, TX
