"Frenzy" to me is that state where rationality is gone; you're acting on impulse and/or instinct, reacting to things rather than anticipating. Your senses are overwhelmed and your cognitive ability has been compromised to the point that you are not in control of what you're doing; you are purely in the moment, and are not necessarily yourself.
So, does this book get us in that realm of sexual frenzy, where nothing but the boink matters, where there is no before and no after, just the sweaty, engorged now? Alison Tyler's intro essentially equates frenzy to the quickie, but expands to a pretty good definition of losing oneself in "the hot liquid silver of a sexual strobe light." I like that imagery a lot, and it explains albeit metaphorically a great deal about sexual frenzy.
You get 60 stories packed into 209 pages. For the erotica bean-counters out there, that's 3.5 pages per story. Things move out very quickly here, and are over just as fast. No time for contemplation, no time for thoughts of consequence. The premise going into every single one of these stories is that you, Dear Reader, are already just as fully aroused as the story's characters. There is no time for seduction or foreplay, no time to build because it's on now, so you'd better keep up, because it's going to be over and done very soon.
There's lots of boy-girl, more than enough girl-girl, and some boy-boy. Plenty of multiple-boy and multiple-girl. Lots of BDSM and power-transfer. And some fun little vignettes that take these standards a bit further afield, like some gentlemen musing on the immense power of delicate female underclothing. The mix is good, and although this collection is packed with stories, there is little repetition.
The vocabulary is unflinching and direct, with no euphemism. Some of the stories push the envelope, like the one about the mourning man who has made plans to join his lady soon, or the Xan West fantasy on delivering unapologetic and unflinching brutality upon a teasing chicken. Strong stuff, most assuredly an adult read throughout.
Props to Janine Ashbless for writing "creamy voluptuous secrecy."
Bottom line: It comes on fast and hard, and is done quickly. As long as you understand this going in, and you're ready for it, this book will be just what you've been looking for.
