Wren - Mastiff Security Volume Two, #6

This is the sixth and final book of Mastiff Security Volume Two, with over 50, 000 words of romantic suspense. Wren Ryland, the head of the Los Angeles offices of Mastiff Security, has been searching for her mother's killer all her life. She became a cop with that goal in mind.  And now, Mastiff has opened doors she didn't think she would ever walk through. FBI Agent Cormac Delaney quickly became her partner in the investigation.
But then she was kidnapped. When she wakes in her kidnapper's care, and Cormac is there, hope turns to fear when he uses a taser to knock her out. She wakes again in his company, not sure if she can trust him. Did he rescue her, or was he her kidnapper? Why did he bring her to Florida to follow a lead on her mother's case? Why does he want to know who her mother's killer is almost as much as she does? Will the answers to all her questions satisfy her curiosity or send her reeling down a dark hole that she won't be able to pull herself out of?
