Hours to Kill by Susan Sleeman

Just as Homeland Security Agent Addison Leigh reaches the pinnacle of her cyber investigation into a firearms smuggling ring, she's attacked and left for dead. Her estranged husband, ICE Agent Mack Jordan, is notified that she's at the hospital in a coma. He may have let his past military trauma ruin their short marriage, but she never gave up on their relationship, and he remains her next of kin.

Mack rushes to her bedside, where he promises to hunt down the man who attacked her. Mack failed her once when he bailed on their marriage, and he's not about to let her down again. But when she wakes up in the hospital, she remembers neither the attack nor ever being married to Mack. And when a second attempt to take her life is made, it's clear something very sinister is going on, and Mack and Addison are in for the ride of their lives.

Another great book by Ms. Sleeman.  In this book we get Mack's story of why he and his wife are separated.  Plus a whole lot of suspense thrown in for good measure.  When Addison wakes up in the hospital from a car accident, she doesn't remember anything about the case she had been working on or that she had been married.  But there is Mack standing there claiming to be her husband.  They race against time to try to figure out what Addison was working on.  As bits of it come back to her, she realizes terrorists are about to attack.  

This is a fast paced, action packed book.  I highly recommend it.  I was given this book by Bethany House Publishing in exchange for an honest review.  I was not compensated in any way.
