C - The Catcher in the Rye
D - Dandelion Wine
E - Every Demon Has His Day 
F - Frankenstein
G - Go, Mutants!
H - The Hobbit
I - Isis (Douglas Clegg)
J - Juliet Immortal
K - Kiss Crush Collide
L - Lord of the Flies
M - The Man Who Mistook His Wife For a Hat and Other Clinical Tales
N - Nine Stories (J.D. Salinger)
O - On the Road
P - Pretty Birds
Q - Quidditch Through the Ages
R - The Reptile Room (A Series of Unfortunate Events)
S - The Scarlet Letter
T - To Kill a Mockingbird
U - Ultimate Blogs: Masterworks from the World Wide Web

Y 
Z - Zen Guitar (Philip Toshio Sudo) 

I couldn't think of any for X or Y.
