Amy and Dan cross the oceans on the trail of a famous aviator, but they find more than they're looking for. Their enemies are becoming more vicious, and the truths they discover more crushing than ever.

When Alfie McQuinn, the notorious jewel thief, is killed on a job, his last words to his son, March, are to "find jewels" and this instruction leads the boy to Jules, the twin sister he never knew he had--and the perfect partner to carry on the family business.

March and Jules are teenage twins, following in their father's footsteps as jewel thieves, but when their latest job goes wrong they end up with one jewel, a sapphire called the Morning Star, one of three cursed jewels--and the only way they can break the curse is to elude the FBI, Interpol, and a gang of international criminals, find the other two jewels, and reunite them.
