“I Dream of Genies” is a whimsical carpet ride of mishaps and mirth. Judi Fennell brings her signature cheeky humor that served her so well during her Mer series, Tritone Trilogy (In Over Her Head, Wild Blue Under, and Catch of a Lifetime) that is smart, sassy, and just a little bit slapstick. Once again the animal sidekicks have a way of stealing scenes from the two protagonists, Matt and Eden. I guess the advice of never working with children and animals is as true in books as it is in film. Obo is pure magic.
