Seriously the sexy guy on the cover is the best part of this book.
The Darkest Fire was like Beauty and the Beast in Hell but BORING.
The Amazon's Curse I read as an ebook and liked it alright but it really should be included as an epilogue to The Vampire Bride. It simply is not strong enough on its own and too short to be included in an anthology.
The Darkest Prison is a reversal of The Darkest Fire in which the woman, Nike, is unattractive and the man, Atlas, is the pretty one in the relationship. It was slightly better than The Darkest Fire but that's not saying much. It's really forgettable and doesn't add anything to the mythos of the Lords of the Underworld series.
The other stuff in the book are just that--stuffing. There is no redeeming value to the Kresley Cole interview (and I LOVE Kresley Cole but this came off as more of a love fest between her and Gena Showalter than something written with the fans in mind). And the character interviews were not even mildly amusing. Overall the whole concept was juvenile in execution.
Bottom line: This book was created to gouge the fans.
This is a book of Showalter's three ebooks. The darkest fire tells the beginnings of the Lords of the Underworld demons, but I found it to lack flesh and really you could read the rest of the series and this story would not matter. The same goes for the Darkest prison although it does give the reader a little info on Paris' Sienna. I would not recommend reading the Darkest prison if you have not read the other Underworld stories.
This book was so horrible I kept checking the cover to make sure Gena wrote this. While I typically enjoy this author, the ONLY saving grace is the prequil to the next underworld book.
