All thriller writers are hacks.They take interesting concepts and turn them into books with three page chapters, every chapter ending in a cliffhanger, and there is always a world-changing mystery and there is always a betrayer. Damn Dan Brown to hell for what he has created. With better execution, this could have been a very moving read, but as it was, I was too busy turning the pages to see what was happening. Moreover, I wasn't surprised by anything. I love Superman, and aside from little pieces of Superman lore, there is really nothing new this book has to offer.
All in all, read if you like thrillers, but otherwise, not worth it. Disappointing.
