Daisy Dawson is just walking home from her AA meeting, minding her own business, when she is grabbed by a masked man. Thankfully, her instincts and self-defense training kick in, and she is able to fight him off -- but not before accidentally pulling a locket from around his neck that ends up being connected to another missing woman.
When Detective Rafe Sokolov (who happens to also be Daisy's landlord) sees the locket, he immediately calls his friend, FBI Agent Gideon Reynolds. Because he's seen the design on the locket before -- on Gideon's chest -- and thinks it may be a clue to the location of the cult Gideon escaped from when he was 13.
So you can see, there are a couple of different story lines here. First and primary is finding the serial killer who tried to take Daisy, but along the way Gideon is also trying to find the cult he escaped from, in hopes of saving the other children who are still there, trapped and abused, and of bringing justice to the men who run it.
Don't get me wrong -- this isn't a great work of literature. There is a lot of sharing and rehashing of past traumas between Daisy and Gideon and some of the other characters. There's maybe a few too many characters, in that "this is a romance series so I need to set up the characters for the next books" way. But I find the rhythm and predictability of romantic suspense to be rather comforting, despite the dark subject matter. Karen Rose is a romantic suspense author I'll always pick up.
