I believe this is probably the weirdest book I've read in a long long time. Or maybe ever. Then again it is the first Bizarro book I read. Maybe I'll look back at it at some point in the future and think it wasn't as out there as I originally thought. 
 As the title suggests, this is a very explicit book. It has very graphic descriptions of sexual acts and both male and female genitalia, but unlike most books with such elements, the intention here is not to so much arouse the reader as it is to just tell the story and inform the reader of the relevant aspects of the journey (yes, there is a journey) the characters go through. 
 Nobody should read it expecting answers by the end. When the book reaches the last page you still don't know what the hell actually happened or why, or how. But if you're in it for the ride, you can most certainly enjoy the experience and find yourself wanting to read more books in the same vein as this one. 
 Overall, the book is totally worth reading and I'd recommend it to anyone who can look at the title and not be weirded out by the notion of spooky female genitalia and the things that crawl inside.
