Freezing Point by Elizabeth Goddard

Casey Wilkes didn't realize her simple human–interest story would put her life at risk–again. After fleeing her home and journalism job in Portland, she wanted to live under the radar for a while. But when her interviewee starts dodging her questions, her reporter instincts kick in and she finds herself in over her head….

Homeland security agent Jesse Mitchell has been undercover as an ice sculptor for months, trying to infiltrate a smuggling ring. He wants to avoid trouble, and that's just what Casey brings. Now someone has a target set on Casey. Saving her could blow his cover, but leaving her unprotected endangers him even more–especially his heart.
