Tiger Eye by Marjoie M. Liu

Psychically sensitive tourist Dela Reese browses for treasures at Beijing's Dirt Market, where an old woman sells her a riddle box for only one yuan. Surprisingly, when Dela opens the box back in her hotel room, a gorgeous seven-foot-tall warrior appears, bearing 2,000-year-old weapons. The warrior, Hari, has been cursed for two millennia to serve as a slave - bereft of his power to shape-shift into a tiger - to anyone who opens the box. Assassins follow Delilah and Hari from Beijing back home to the U.S., where Dela and Hari soon find themselves in the midst of a war between Chinese crime syndicates. The reappearance of Hari's age-old nemesis, the Magi, who has been searching for Hari since he was imprisoned in the box, jacks up the suspense.

First in the series of the Dirk & Stelle paranormal romances. This was suprisingly good and very sensual in an erotic way. I actually read the 2nd book first so it was good to go back and figure out who these people are. All the characters are well connected and make me want to know more about this group. I'm glad that she has written several and look forward to reading more.
