Code Name series by Christina Skye

Code Name: Princess
2nd book in the Code Name: series. This one features navy SEAL Hawk MacKenzie and hotel investigator Jess Mulcahey (sister to FBI agent Summer Mulcahey, the heroine from Nanny). The pair come together under tumultuous circumstances when Jess, pretending to be minor royalty, bribes a hotel manager into upgrading her to a nicer room, which turns out to be Hawk's digs. Although the hotel has changed locks, it doesn't deter Hawk, who gains entry with a "highly illicit piece of technology" and catches her in the shower.

Hawk is hot on the trail of a stolen government lab animal, and Jess is afraid the hotel staff will seek revenge on her for a bad review. Neither has the time or patience for the other's drama, but they are thrown together time and again in the genre's usual fashion-chasing the bad guys through the fog and rain of Washington State's Olympic Peninsula, easing sexual tension in a stalled hotel elevator and tracking down the lab animal, an adorable koala bear.

I like romance books that feature characters from other books. It was interesting how the murder part of this book is skimmed over leaving one almost to feel it didn't really happen. The main focus is on the two characters as their characters clash and sizzle at the same time. I'll look for her other books.
