Oh, I have read this one! It was good! I think I've read maybe three or four in the series. I also read Acheron though and that book went completely downhill. Just beyond. Acheron is a lovely, wonderful character and it was traumatizing reading his story. Too, too much. I read a couple after and they were fine. If I were more into YA, I'd read her Chronicles of Nick. There's so many to love though, so enjoy.
Sherrilyn Kenyon is the SOLE reason I "came back" to romance reading. I've read through ACHERON in the Dark Hunters. It's a fantastic series, especially the first half dozen. Hope you get a chance to read them all.
