Love over duty, book 1: Under fireScarlett Cole2017

HE CAN TAKE THE HEAT.
Hot, hard-bodied Sixten Rapp is a former SEAL who’s raring to begin his brand-new civilian life. He and his Navy “brothers” start a security firm that offers the kind of services only a team of military-trained professionals can provide. But nothing prepared Six for his new client: an innocent woman on a mission to improve thousands of lives. . . unless someone takes hers first.

CAN SHE HANDLE THE FLAMES?
Dr. Louisa North knows time is against her as she tries to create a “miracle” medical treatment for a disease with no known cure, until she creates a sample so powerful that the wrong people want to use it as a chemical weapon. At first, Six is unwilling to accept Louisa as his client. But soon he realizes that the danger is real and that there’s much more to this plain-Jane scientist…including a burning passion between them that neither of them can resist. And now that an enemy is on Louisa’s trail, Six will do whatever it takes to protect her—or die trying.
