Rose Ann can't believe her good luck. Her grandmother, Glory, needs a last-minute roommate for her bridge-tournament cruise to the Caribbean. But Glory doesn't really need a companion. She's eager for Rosie to meet her friend's grandson, Neil. Once Rosie is aboard the ship, though, someone else catches her eye--a boy her own age, who introduces himself as Ricky Diago. But after the ship sails, something doesn't seem quite right. Rosie sees Ricky's uncle, Mr. Diago, but not Ricky. Even stranger, Neil swears that Mr. Diago is actually a famous Cuban baseball player from the Cincinnati Reds. When Rosie is approached by another boy who claims he's Ricky Diago, she finds herself caught in a high-stakes game of international intrigue with life-or-death consequences. Who is the real Ricky Diago? And how far will Rosie go to help him?-- P. [4] of cover.
