I found this author by reading his really funny VOYA column, "Where's Lubar" (pdf of the one I saw) and just had to give him a try.

Wouldn't it be great to find out that all the trouble you were getting into was really caused by some special paranormal power and that you could learn to control it instead of letting it mess up your life?
This is an easy, quick read. I think even younger (9-12) kids would enjoy it. It features Martin Anderson, a 13 year old boy who gets shipped off to Edgeview Alternative school (after being kicked out of other schools and groups for mouthing off to teachers) and who figures out that his new friends are really quite special (Cheater is telepathic, Trash is telekinetic, Flinch is clairvoyant, etc.)
You can read the first chapter here if you'd like.
