Forget about genies who are fiery spirits or live in lamps. The Twin Jinn at Happy Jack's Carnival of Mysteries is a story that will make readers believe they are real. Jute and Fina Jinn, brother and sister, and their parents are enchanted beings who seek refuge at a traveling carnival after escaping their cruel master. While in hiding, the twins must pretend to be 11-year-old humans, but mischievous and curious, they sometimes get carried away. Who could blame them? The twins have the power to fly, be invisible, and use spells. Thankfully, they have an outlet as carnival kids assisting their parents in a magic act and making friends with their fellow performers, including a shy boy. Still, amid the fun, there is danger for the Jinn family because their former master, a man with evil intentions, is desperate to get them back, and having a magic act that turns out to be a huge hit could be their undoing.
