Captured, by S.J. Harper
This bookmark advertises a series that features FBI agents Emma Monroe and Zack Armstrong. It says, "She's cursed. He's damned. Together, they make one hell of a team."
It's misleading though. The website FallenSiren.com does not have a link to a free e-book, just to an excerpt on the publisher's website.
The excerpt was too short. There was too much emphasis on a drooling introduction to Zack without giving me any reason to care. Instead of making the reader care about him through the story, the author takes short cuts by comparing him to characters fleshed out by others, James Bond and Seeley Booth. Those guys aren't even book characters.
Only at the very end does the reader learn much about the narrator–a siren, cursed by Demeter. We aren't given enough to care about her.
Captured is the fourth book in the series and the author may be one of those writers who assume only people familiar with the other books will read this one. That's too bad because I've often been lured into a writer's works by reading a later book.
