On the beautiful Hawaiian Islands, not all is paradise in this high-stakes, action-packed romantic suspense. Jiang Ying Yue believed her kidnapping was a case of wrong place, wrong time. Why would anyone want to harm her? But when her rescuer Azubuike Anyanwu discovers a traitor in her father's organisation, Ying Yue realizes that she's become a pawn in a dangerous game and whoever has captured her won't be satisfied with just making her disappear. Azubuike Anyanwu built his life around the Search and Protect Corporation, with his canine partner Buck at his side. Taking on a contract to protect Ying Yue during her time on Oahu seems straightforward but nothing is ever simple. His team has caused too many problems for a human trafficking ring with international support and now Search and Protect has been framed. Zu will have to choose between saving Search and Protect or keeping Ying Yue alive.

As a K9 handler on the Search and Protect team, Arin Siri needs to be where the action is--and right now that's investigating a trafficking operation in Hawaii. When an enemy from her past shows up bleeding, she's torn between the desire to patch Jason up or put more holes in him. Then again, the hotshot mercenary could be the person she needs to bust open her case. Jason Landon's team had always been about taking the contract, getting paid, and not asking questions. But after his last mission went south, he started to get curious. His questions quickly drove him out of his mercenary group and off the grid. Now, the only people he can think of to help him are the Search and Protect team -- and the dark beauty who is as ready to kill him as she is to bed him. And he's totally ready to risk the former for the chance at the latter. But he isn't the only person with a target on his back. Arin's in danger too, and he'll do everything he can to keep her safe.

Inexorably drawn to her, he'll have to find a solution to the people threatening Ami's freedom...and he'll need to survive his best friend's temper when she finds out he's fallen in love with her younger sister.
