How do you ensure that the books you stock are winners and not wannabes? Start with tales that kids already enjoy — like the ones told by their parents or caregivers. “The stories started with trips to places I had been lucky enough to have visited,” begins Nabila Khashoggi, author of the new Spartan and the Green Egg series. The debut book in the series, A Trip to the Rainforest, weaves together a compelling story about a circle of friends and environmental concerns. Elements of pure imagination entice young readers: the Green Egg is an alien spaceship that uses power and technology to help friends Spartan (with rescued canine sidekick Grimm), Tor, Katie, and Max on their journey.
