Mortal Danger (The World of the Lupi, Book 2)

Former cop Lily Yu has her sister's wedding to attend, a missing magical staff to find, and now must deal with her grandmother's decision to return to the old country. Lily could turn to the man she's involved with for advice, but for all the passion that flares between them, she doesn't really know Rule Turner--she's just bound to him for life. Rule happens to be a werewolf, and Lily wonders just how far she can trust him.
