Thirteen Across

THIRTEEN ACROSS. Seven stops. Seven sets of clues. A race against time. Conspiracies. Lies. Will FBI Special Agent Kate Morgan survive it?

Kate Morgan is headed to a U.S. Senate hearing when Phillip Barnes makes his attacks on the nation’s capital personal. Thirteen Across is a sign of the events to come and Kate finds herself thrust into the center of a grander conspiracy.

Barnes reveals an unfolding puzzle—its challenge charts a course, one that expires at midnight. Puzzle solutions and destinations expose a dark past.

The FBI brings in real-life puzzlemaster, Will Shortz, to riddle out stops, while Kate works the frontlines to save seven victims. Kate must log the tours and save those that she can. And the final destination is a place where Kate must atone for her past sins. What Kate thinks she knows about her past is tested as is her ability to survive her trials.

Thirteen Across is a puzzle in a puzzle.
