Aiden Willingham has lived a hard life. As a Navy SEAL, he agreed to take part in an ultra-secret government testing program. The company running the program, the Silverstone Collaborative, has produced a serum from an Amazon plant that's been proven to enhance physical abilities and mental fortitude. Problem is, men died during the testing, and it's time for the company to be taken down before more men die. Aiden, as well as three others, escaped the camp with evidence of the company's wrong-doing. Now they're in a race to expose them. They've already lost one of their team, and the Collaborative's mercenaries are converging. Angela Holloway knew the military man with sadness in his eyes was trouble as soon as she saw him hanging around the site of a murder. Uncooperative, he stonewalls her investigation, but draws her in when the badge comes off. Aiden has scars, both internal and external, that make her heart ache. It's a serious no-no getting involved with a suspect... too bad her heart isn't listening. As details come to light about what's going on in her city, she has to fight for what she believes is right, as well as the man on the wrong side of the law.
