Nuts and Bolts - Nailed It Home Reno Mysteries, #5

Ex-cop Rowena Summerfield would do just about anything for longtime friend Ryder Tompkins. When he discovers he has a half sister he never knew about and pressures Ro to use her investigative talents to help him find her, she can't say no. But boyfriend Chuck Dawson's offer to accompany her to Atlanta might complicate the search. Is she ready for so much togetherness? What begins as a simple missing-person case escalates to a danger-filled odyssey when they learn the woman has fled town, taking all her worldly goods except a bloodstained cocktail dress.
The hunt is on as they follow clues cross-country from one town to another. But they've left a trail of their own, and the missing woman's enemies now threaten Ro and Chuck-not to mention their friends and family back home in Florida. Ro is torn. If they go home to protect their loved ones, they'll leave Ryder's sister in danger, but without the backup of Ro's police colleagues, they don't have the resources to face a killer.
As Ro and Chuck work their way through a labyrinth of challenges, their partnership evolves beyond attraction. Is it strong enough to withstand Ro's sneaky moves to solve the case while keeping him out of danger?
