Batgirl and Supergirl face familiar supervillains and old colleagues from the DC Comics Universe in these fast-paced adventure chapter books. Harley Quinn hurtles through time with the girls when they find a kaleidoscope that transports them to different eras and places; Zod breaks free and attempts to take over Earth; the Cheetah steals an ancient necklace from a museum that gives its wearer unprecedented power; and the Joker installs a hypnosis app on people’s phones, causing them to laugh helplessly at everything while he and his goons rob, steal, and cultivate chaos. Supergirl and Batgirl swoop to the rescue in each tale, using their combined technology, superpowers, and intelligence to save the day. Bright full-color illustrations break up the action-packed, exciting chapters, and short, level-appropriate sentences make these a great addition to early chapter book collections. Each book contains a glossary, discussion questions, and writing prompts at the end of each story. VERDICT: Purchase where DC Comics stories are in demand.
