3.0
I liked the humor, but I had two main problems with this book (mild spoilers ahead): 1) free, no-rule magic system. Things just happened when it was convenient, there was no cost to using magic. Skulduggery literally could flick his fingers and send enemies flying. And 2) Skulduggery was simply invincible. He could be tortured, thrown off a cliff, swallowed by a wall... he'd just shrug it off and move on. Also, he happened to have a very convenient immunity against the ultimate weapon, so there goes the tension. Too bad, I really liked to enjoy the series much better. I may read book 2 still, but we'll see.
