One decision changed his life.

Nathan Hollister nearly died in a war zone and the experience made one thing crystal clear-breaking off his engagement was a terrible mistake. He arrives at his ex's ranch to make amends, but gunfire erupts before he can.

Someone wants her dead.

Cassie Miles is used to being abandoned, first by her mother and then Nathan. But when an attempt is made on her life, she can't protect herself and the horses she's rehabilitating. Accepting Nathan's help is the only answer.

A hazardous mission.

Nathan won't let anyone harm Cassie. Convincing her to give him a second chance, however, is impossible. As the danger creeps closer, the risk heightens. One critical error could cost Nathan everything...again.

Critical Error is the second novel in the gripping Triumph Over Adversity series, but each book can be read as a standalone. If you enjoy stories featuring brave military heroes, intense suspense, and heartwarming romance, then you won't want to miss this captivating read.
