Blind Trust by Natalie Walters

Lyla Fox knows she has a reputation at the SNAP Agency for impulsivity, but when she receives a threatening letter from a man she helped put in prison, she can’t stop herself from going all in to find out why he’s coming after her. Unfortunately, she’s going to need the help of the one person who questions her reckless choices more than anyone else.
Explosives and weapons specialist Nicolás Garcia agrees to help Lyla in order to keep her safe, but her recklessness continues to be a major concern, especially when her investigation into a conspiracy puts a target on her back. Dealing with bombs is dangerous. Working with Lyla is proving to be just as treacherous–to both the mission and his heart.

Natalie Walters closes out her SNAP Agency series with a bang with this nail-biting story of a deadly government conspiracy, an unlikely couple, and an ending that will leave you breathless.
