All for Quinn by Kay Hooper
He's an international jewel thief trying to catch another international jewel thief!\xa0 She's a museum... employee?\xa0 Evidently?\xa0 It's All for Quinn by Kay Hooper, a Loveswept that's also somehow fourth in a series with real continuity and the expectation that you have read the others! And yes, the cover on both Amazon and Goodreads is just a photo of the book somebody took\xa0with flash.
It's caper time!\xa0 No serious triggers in this at all, just good ol' caper stuff like chloroforming and Interpol.
