Zander thought he was taking on a run of the mill bodyguard position… When ex-SEAL Zander Smith signed up with Stryke Force, he imagined he’d be escorting stuffy billionaires to conferences. Never did he expect to meet Kenzie, a beautiful girl too scared of the outside world to risk leaving the safety of her mansion, even if there was a crazed killer lurking inside. Kenzie immediately feels safe with her new bodyguard, and is eager to spend more time with him, but then there’s a knock at her door… At first Kenzie feels lucky to have been asked out by both the wildly handsome football player next door, Ty Crenshaw, and the hot ex-SEAL she hired to protect her, but the excitement is short lived when clues point to one of them having a few skeletons in his closet. Murderous skeletons, that is. One of Kenzie’s suitors has an ulterior motive, of that she’s sure, and she has to unveil the wolf in sheep’s clothing before it’s too late. less
