I have only heard of a few of these books...Lol!!

Where the Red Ferm Grows!!
joanofark, Where the Red Fern Grows is such an awesome book! I cried a lot though.

Im not really sure i have a favorite book..
Vette, isn't D.C. Andrews the author of Flowers in the Attic? I looked at that book and was going to buy it, but, I didn't have enough money with me at the time I'll have to buy it some time though

Thank you all for replying!
