Stuck on You by Patti Berg (2003, Paperback)

It's common knowledge in Plentiful, Wyoming, that bookstore owner Scarlett O'Malley imagines trouble brewing everywhere. Of course, real trouble bubbles over the day an enigmatic stranger named Logan Wolfe shows up in town. The outsider's one hunk of a guy, with a smile that could knock a redhead off her sky-high heels. But when a mysterious woman literally drops dead at Scarlett's feet and the town's wealthiest widow disappears, suspicion falls on the secretive man. Scarlett is positive Logan's up to something -- but is he out to scam the people in town, or steal her heart?

The last thing Logan wants is a screwball sleuth dogging his footsteps and digging into his past. The ex-cop came to Plentiful to escape the madness of Las Vegas and to ditch bad memories, not to have some zany redhead with a man-killer body mess with his peace of mind or history that's better off buried. But Logan can't help admiring Scarlett's spirit -- or the gold stars dangling from her belly button ring. And when her wacky investigation takes a surprising turn, Logan finds himself glued to Scarlett's side, helping her look for clues, keeping her out of trouble -- and maybe falling in love ...
