I read this book in a day and all I want to do right now is read the next one. It's that good. The narrator, Jorg, is the opposite of the typical hero or protagonist. He's a pretty awful person, yet you root for him anyways. You want him to succeed at whatever crazy scheme he's come up with, even though it will mean the painful, miserable deaths of good people. Jorg's main (only?) redeeming quality is his intelligence. 
 Actually, I just realized that Jorg is a lot like Artemis Fowl. They're both ridiculously young, both insanely intelligent, and both people that you wouldn't expect to root for. Unlike Artemis, Jorg does the dirty work himself. For example, if he wants someone dead, he stabs them himself. The book gets pretty violent and kind of dark in places. If you're like me and you're reading this because you loved Prince of Fools, be warned- this book is completely different. I loved it just as much, but Prince of Fools has comedic aspects, while Prince of Thorns definitely doesn't. Jalan (from Prince of Fools) and Jorg could not be more different. Just a heads-up. However, they're both worth reading in my opinion. 
 As Terry Brooks wrote in his review of Prince of Thorns, "It is like a train wreck from which you cannot look away." That's a pretty accurate way to sum up Prince of Thorns. I could not put this book down.
