Never do a favor for a friend. So why is March McQuin dangling upside down twenty feet above a stone floor in the middle of the night, instead of tucked in bed like a regular kid? Along with his twin sister, Jules, he's set on stealing a set of stunning diamonds. It should have been an easy job, in and out. Except another thief got there first. March and Jules are lucky to escape with their lives, and one measly stone. Now the botched heist has created a world of trouble. The stone they grabbed was the Morning Star, one of a trio of famous sapphires, and it's cursed. The theft puts the twins and their friends in the crosshairs of Interpol, the FBI, and a vicious adult gang of criminals. And worst of all, the only way to break the curse and set everything right is by pulling off two more impossible heists...and stealing the other two sapphires in the set. Break out the black gloves. Lay out the masks. There's a full moon coming, and jewels to steal..
