Deadly Dance - A-Tac, #6

As the intelligence specialist for A-Tac, a black-ops CIA unit masquerading as Ivy League faculty, Hannah Marshall is used to working behind the scenes. But when a brutal murder hits too close to home, Hannah finds herself in the middle of the action, falling in love while racing to outwit a sadistic mastermind. A KILLER CLOSES INAfter the death of her A-Tac partner, Hannah doubts everything she thought she knew about love and loyalty.
When handsome Harrison Blake joins the team, she's reluctant to trust him-or to act on her intense attraction to him. Then Hannah receives a podcast of a gruesome murder, and the only person who can help her find the killer is Harrison. Harrison has spent years trying to hunt down the cunning monster who killed his sister. Now investigating with Hannah, he faces a shocking possibility-his sister's murderer has resurfaced.
As the danger escalates, Hannah and Harrison grow closer, and the desire simmering between them ignites. After Hannah disappears, Harrison has only one chance to save the woman he loves.
