In defense of the author, he knows his CIA history. I will give him that. But this book is one weird piece of writing.
Is it sci-fi? Is it a thriller? Is it New Age? Is it Crypto-Mormon? (No insult to Mormons, here) Halfway through the book I still wasn't sure. Really. I wanted to believe. I love X-Files and Star Trek...but this one misses the mark.
First of all you have this unkillable guy named Chalmers. He fights in WWI and doesn't die. He doesn't age, so he signs up for WWII and also doesn't die. He has visions of angels/beings that rescue him now and again. He has no love life, doesn't relate to other human beings, doesn't LIKE anyone in particular or believe anything in particular, but he gets consulted on everything everywhere, in every generation. Teddy Roosevelt, Richard Nixon. It's all the same to the genius Chalmers. Oh, and there have been versions of Chalmers all through history.
The angels, or alien beings, or whatever they are, are supposedly in charge of planets. They have names like WON, and TU, Tha-Ree, Vor, and Fieva - you get the idea. Their "headmaster" is (surprise!) named Ga'Lawed. There are twelve of them. And every day (in eternity) they are sent out to seed new worlds. And the day they go out is called SUNDE. Get it? Sometimes they leave the apes alone to evolve, sometimes they interbreed. So, one of these angels (Number Fieva) becomes disgruntled with the boredom of his eternal chore and gets the naughty idea to interfere in an evil way, and that is where all the evil aliens (Roswell, UFOs, greys and Reticulans) come from. It is convoluted, weird, and could have been fun or scary or compelling. Unfortunately, it is just boring.
I would not recommend this book to anyone.
