The Thumb Drive Of Saluko Jones

A 2066 novel by Chuck Cloutier
"A cruise ship in the middle of the Atlantic. A spy on the verge of
 death. Saluko Jones has only seconds to live and his handler is nowhere
 to be found. The only one there is Jill J. Guff, and she’s just a data 
entry clerk for the cruise line.''
But when the dying spy 
hands off his thumb drive to the frightened woman, he sends her on a 
quest beyond imagination, an adventure to end all adventures. Jill is 
not only going to have to decode the drive and find Saluko’s handler, 
but survive the men who killed him.''
From Chuck Cloutier, author of The Maze Series, comes the spy epic of a lifetime."
