Paranormal Security and Intelligence Operative Duke Marlow has a new mission: find, interrogate and possibly eliminate the target - Mercy Deluca. He knows looks can be deceiving, but it's hard to believe the beautifully quirky woman running around in a superhero t-shirt is a viable threat. The sexy little biomedical engineer quickly proves she is more than he bargained for and Intel has it all wrong - she's not the enemy. Far from it. Intel also forgot to mention one vital piece of information - she's Duke's mate. This immortal alpha werewolf doesn't take kindly to her being in danger.
When Mercy accepted a position within Donavon Dynamics Corporation, she thought it was to help cure disease and to make a difference for mankind. She had no idea what her new career path truly entailed - monsters masquerading under the guise of scientific research. Unable to stomach the atrocities she's uncovered, she reaches out through what she hopes is the proper channels, asking for help. Mercy gets more than she bargained for when a team of paranormal hotties show up on her doorstep ready to take down the Corporation. One in particular is able to get under her skin, both aggravating and exciting her in ways she can't explain.
