Kidnap in the Caribbean. by Lauren St John (Laura Marlin Mysteries)

Laura cannot contain her excitement when she wins a trip to the Caribbean for herself and her uncle, Calvin Redfern, especially when her best friend, Tariq, and her three-legged husky, Skye, accidentally find themselves on board too. But when they dock at Antigua, they discover that Calvin Redfern has vanished, and Laura and Tariq are about to be kidnapped by the fearsome Straight A gang. Dramatic escapes, an erupting volcano and a race against time to stop the deadly undercover 'Marine Concern' make Laura's second adventure every bit as exciting as the first.
