If you've read Wilson before, then you should know exactly what to expect from this book. I wouldn't call him a one-trick pony, but he certainly has his themes and he sticks with them. This book is more about its ideas than its writing: a mash-up of Timothy Leary, Joyce, a mostly-correct understanding of quantum mechanics, sex, drugs, conspiracies, politics, mysticism and the absurd.

The title draws upon quantum mechanics, and Wilson seems to be attempting an illustration of Everett & Wheeler's many-worlds interpretation of QM. Hence, every character occupies multiple personalities, perspectives and genders as we jump through books and universes.
While this is a more thoughtful treatment than the slew of "quantum" new age books we see today, I'm always extremely reluctant to apply quantum anything to day-to-day life or psychology: quantum mechanics is a theory about subatomic things, not about people or brains. While there are many interpretations of what it all means, these do not form a part of the physics proper, are open to debate, unclear in their implications, and are far from settled. So, I'm hesitant to take a glance at the Everett-Wheeler interpretation and then exclaim "there's a universe where I grew up to be a circus clown!" Even if such a statement is true, it's hard to say in what sense it is true since all these separate universes are by definition isolated and cannot communicate in any way: you may as well postulate the existence of an undetectable pink unicorn. It affects nothing.

That digression aside, I thought this was a fun read, though it lacked the sheer variety of the Illuminatus trilogy. I did actually laugh out loud at points, which I rarely do with books. The characters and their worldviews are all interesting and unique, but thoroughly familiar if you've read enough Wilson.


EDIT: I'm not sure I even want to get into the question of quantum entanglement here. Needless to say, it's not what you've read in this or other books. It does not mean you're connected to everything you've ever interacted with. It does not provide a method for telepathy or synchronicity.
