Harper Kane is taking a break from training for the Olympic swimming trials to visit her brother Bobby in Oregon. She and Bobby are headed for his home when they are ambushed by unknown snipers and he is murdered. Harper barely escapes the killers, but they are hot on her trail. It seems Bobby has left her a syringe filled with an unknown serum and a flash drive containing information worth killing for. When Harper is accidently injected with the serum, she is given powerful, killing psi abilities.

Rome Lucian is an agent for the government. After an incident in which the men under his command were killed, he has locked down his emotions and follows orders without question. His order to bring in Harper, dead or alive, is just another job, one he doesn't question, until he meets her. Against his better judgment, he decides to trust her and help her in her quest for revenge. But he again questions his decisions after he sees Harper in action.

Amy Rench's FALLEN ROGUE has a great premise that doesn't quite live up to its potential. The first few chapters are exciting and fast-paced, but once Harper goes on the run, the plot seems to fall apart. Harper's motivation is clear, revenge for her brother's death, but Rome's motivation is less clear. I had difficulty understanding how Harper could trust him, let alone fall for the guy. For me, this book failed to deliver a believable adventure.
