Call me a simple man and not in order but here goes:
1st novel I read that I loved and still do.
Where the Red Fern Grows By Wilson Rawls
Intensity by Dean Koontz
The Day of the Triffids By John Wyndham
Three By Ted Dekker
The Chronicles of Narnia (entire series as 1) By C.S. Lewis
The Grapes of Wrath By John Steinbeck
A Man Called Simple By Langston Hughes
Native Son By Richard Wright
Deliverance By James Dickey
The Silence of the Lambs By Thomas Harris
Invisible Man By Ralph Ellison
There are so many others that could be listed, but off the top of my head this is a good start.
