I've read all four, because I'm a nerd.
Thought the first three were mad dope, the fourth was wack, and I've been waiting on the fifth for like a year and some change (which is a lot less than most people). It's worth picking up the series since the first 3 volumes are the best 3 volumes of fantasy fiction I've ever read from any series, ever. But, the fourth is buns and something tells me the fifth (and all subsequent volumes) will also be buns.
my ice cool as the night air
two fives flare
glare through your cartier eyewear
and knock ya newborn out the high chair
