Have You Seen Her, by Karen Rose is a great serial killer mystery story combined with a hot romantic tale that really grips your attention.  The characters are well developed and interesting and the story unwinds at break neck speed.  The heroine is a somewhat conservative school teacher, who is so shocked by her own sexuality that she spends a lot of her time trying to control herself, and not jump Special Agent Thatcher's bones.  So much so, that she doesn't realize just how much danger she's in.  The killer is scary, well hidden and until the very end undiscoverable, but it's whose been helping him that turns out to be the greatest monster.  A great read if you're looking for romantic suspense.  The author did a great job on this!
