Nightshade: Professional troubleshooter Colt Nightshade is a man who likes working alone. But when he's forced to team up with buttoned-up Lieutenant Althea Grayson to find a missing girl, he discovers that getting through his sultry partner's icy exterior is a challenge he's more than ready to accept.

Nightsmoke: He'd a reputation for being aggressive and annoying - but if Natalie was going to save her buisness, she needed arson investigator Ryan Piasecki's help. But the classy executive was used to being in control, and Ry's arrogance was infuriating.
