Love McCammon, and think that 'Boy's Life' is one of the best coming-of-age books out there. Only one of his I didn't read was 'Gone South'. Premise seemed goofy. Only one I didn't like was 'Swan Song', even though it had many cool elements. The writing seemed a little frenzied and he seemed to be drawing it out to 'Stand' length and for no good reason. A goofy book, certainly.
'Yellowjacket Summer' was the best story in 'Blue World', I think, and the first one.
Anyone ever read 'Under the Fang'? He edited it and has two stories in it. It's a compilation of stories about life on earth after the Vampires arise and take their rightful place as top of the food chain. Some of the stories of resistance in there are unbeatable. (Spoiler warning, although not really since the book is out of print) There is a scene where the story's hero throws a spear at a vampire overlord sitting at his banquet table, and the vampire catches it an inch from his chest, then holds it while he makes some witty remark. Without hesitation the guy leaps across the table and just drives the spear right through him. Good stuff.
