I never got into most the classics. I always found them hard to read. However, I do like the Hobbit, Treasure Island, The Adventures of Robinson Crusoe, and Horatio Hornblower
I read the adventure stories like:
Jack Reacher by Lee Child
Dirk Pitt by Clive Cussler
Manny Williams by Rick Murcer
The Prey series of Lucus Davenport by John Sandford
Hunger Games by Susan Collins
Fahrenheit 451 by Ray Brandbery
Hannah Sampson (Diving) Mysteries by Kathy Brandt
