Ambrose revisits characters from her 2008 debut, Lie to Me, in this lighthearted romance. Janet Aims decides to erase her ex-husband from her life by hocking the jewelry he gave her. What she doesn't realize is that one gaudy necklace is actually part of the famed Pellinni Jewels. After someone breaks into Janet's car and condo searching for the rest of the jewels, Janet turns to reformed jewel thief Rocky Hernandez for help. He vows to keep Janet safe by tracking down the jewels himself, even if it means getting in touch with his unsavory former associates. Ambrose deftly balances Janet and Rocky's steamy relationship with the suspense plot, though at times she gives too much emphasis to secondary characters. (Dec.)
