Just terrible. I don't even know why I finished listening to it - I guess because I have enjoyed some of Streiber's previous work and was hoping it would get better. It was saccharin, maudlin and redundant. The basic premise and driving story line, sans all the ridiculous Harlequin Romance-style details with repetitive and bizarre descriptions of bodily functions, odors, tastes and unnecessary lame sex, could have been summed up in half the time and to much better effect. This was supposed to be a sci-fi thriller not a sappy homily on love of family. I am actually kind of shocked it was so bad. I want to scream to get it out of my head!

Having heard many an interview on Coast to Coast AM it feels like he is writing what he thinks he is actually experiencing a lot of the time, for example in an interview this year he talks about passing into parallel Worlds whilst driving and later a book with the same idea is released. I wonder if he actually lives inside his stories or his stories are based on what he believes he is experiencing. Either way this is a dreadful book that jumps around too much to make any sense, The Grays is a far better.

Stephen King spins immersive yarns that make up for his anticlimactic endings. Mr. Strieber does the same for the first half of the story. As long as I could follow his protagonists and antagonists, it was an enjoyable ride -- especially with the nimble and evocative voice work of reader Joe Barrett.

The tease toward the didactic in Martin's transformative experiences seemed short on an adequate supply of gold leaf. The references felt out of place in the context of this story, where a lighter touch would have been as, if not more, effective.
*
The long and fun ride hits pot holes in the final chapters. Characters suddenly display amazing attributes, convenient for the storyline, by having historic information about the character quickly backfilled to explain the unexpected turn of events.

Strieber may have thought that the alien location of these scenes offered a blank canvas, but without any reader preparation, this technique was more like early draft notes for a different book had been left in the wrong manuscript.

I like buying audiobooks that have bad reviews just so I can disagree. And some of the bad reviews for this book are quite harsh. But in the end, I tried my best to see something that just wasn't there. The premise for the story could have been so much better if lizards weren't involved. The idea of parallel universes hasn't been done that well in the past, and still hasn't. This book goes back and fourth and even though you do know who is speaking, it is too disjointed and unclear. Perhaps it would work as a movie, I don't know.
But the whole idea of the book had very little to relate to the doomsday theory of 2012. This was just implemented as a recognition of people starting to take notice of the potential this theory has. The actual story of this book would read exactly the same if it were situated in any time period.
I thought this would be an interesting doomsday story, like "One Second After" or "the Road". but it wasn't. It had a much stronger focus on Science Fiction. So if you like that sort of thing, fine. But for me, as much as I tried, this book didn't work.
The only saving grace was the narrator, the veteran of the audiobook world, "Joe Barrett". He never disappoints with a vast array of tone, accents, characters and clarity of voice. Joe is the consummate professional, I've listened to his other work and it is clear he was born to be a story teller.

A very poor attempt to provide a fictional "unified theory of everthing" to all things supernatural. The whole thing has so many holes in logic and reason that it constantly took me out of the suspension of disbelief. I have enjoyed other books by this author but this one is not recommended.
