His hot number - Shannon Hollis

When rookie narcotics investigator Linn Nichols has to talk dirty to a suspect for a case, she's not sure she can do it. How's she supposed to get the respect of her co-workers that way? Besides, she's no seductress.

But once Linn gets on the phone, she becomes "Caroline," a sexy siren few can resist-including her team leader, Kellan Black. The only problem? Linn doesn't know if Kellan wants her for who she is or who he wants her to be..

After Kellan hears Linn's hot, sultry voice on the phone, he's enthralled. She might be undercover, but her sex-filled words seem to be all for him. As soon as she hangs up, though, she's back to being tight-lipped and in control. Or is she? Linn and he have to work together on the case, and that means spending lots of time together-day and night. Kellan likes the hot and intense side of his partner, but can he lure her out permanently?
