Threshold by Kevin Barry O’Connor

The explosion.


The white lights beckoned her from this life to the next. A hand reached down. Marine Captain Cat Fahey stretched toward it, night after horrific night, as she lay on the park bench in Philadelphia. Once a military legend, now homeless. She knew, without doubt, the hand reaching to her was her ancestor, warning her that an assassination of a world leader would soon take place in Philadelphia.

There was only one person who would believe her.

She had to find Key Murphy.


Threshold matches the fast pace and excitement of Robert Ludlum’s Bourne Identity thrillers and the clever plotting of Lee Child’s Jack Reacher series.  – Michael Ferry  BookTrib Reviews.
