Biochemical Reaction by Amy Ruttan

An attraction like no other…

Former Navy Seal Jack Crane walked away after a chemical attack wiped out his platoon and scarred him, forcing him out of the military–the hardest thing he ever had to do…Until Omega Team contacted him to protect an undercover agent at a secret lab.
Lisa Morgan had nothing to lose when she took on the assignment to uncover Bio-Tek’s dark secrets concerning the deadly chemical agent that killed her brother and cost her the only man she ever loved a decade ago when he walked away.
When the man hired to protect her turns out to be Jack, she’s forced to trust with her life the man she couldn’t trust with her heart, and make sure the antidote for that terrible chemical gets into the right hands before it’s too late.
