Query: Blood Sex Magik

This book makes no apologies. It's sexually graphic. It's violent. There are no pure of heart heroes. All fine qualities that make this book of dark fantasy enjoyable to read.The short stories are well done. The author doesn't waste pages and each story comes to a satisfying conclusion. All the short stories except the first revolve around sexual fantasy. It's not [x-rated], per se, but it wouldn't take much effort to move it into that category, if you catch my drift.The included novel, Caliban, is an engaging story centered around the struggle for personal power and revenge. A bit on the bleak side, but hey, this ain't no Dean Koontz novel, thankfully.Recommended.
