Fever

Matt "Loose Cannon" Shannon is an ex-FBI agent turned security chief for the world's largest cruise line. In the novel's opening, Shannon's stepbrother, Jack Fontana, gives Shannon what looks like a game controller--and before he knows what he's done, Shannon has sunk a freighter in Miami's shipping lane and his fingerprints are all over the device that sent the signal. Only once he's cornered does Shannon learn his stepbrother's real plan--a cruise ship job that could make enough money to last their lifetimes.
