Query: A great read. Again, again, again, and again.

The five novels in this book are genius. Alan Mendelson, boy from mars, takes youn through a boy going through being the new kid, goofing off with another weirdo, the wacky Klugarsh Mind Control, and... well I just can't give away the rest! I have to say i have a soft spot for The Last Guru, its so just... cool what happens to the boy :). This is an EXELLENT book for anyone to buy, I've read it so many times i tore off both covers and three pages. A great book to love and read again, again, again, and again.
