Turn off the television and teach your children how to think.

*I do not read or write anything in the "Comments" section.*
You have been given some good choices, there. You may also want to go to your local library and ask the librarian for suggestions.
A few other authors I might suggest are Margery Sharp, Madeleine L'Engle, E. Nesbit, Edward Eager, Kenneth Grahame, L.M. Montgomery, John Steinbeck, Charles Dickens, Sir Arthur Conan Doyle and Marguerite Henry.
Please note that subject matter and writing styles of the above listed authors vary (from mystery and fantasy to animals and history); as I am not sure what genre appeals to you.
You also don't have to limit yourself to the 'young adult' section. Browse the shelves at the library or the book store and pick up whatever catches your eye. Read the synopsis on the dust jacket or leaf through a few pages. You'll soon discover an author you want to read.
Then, after you've read everything that author has to offer; repeat the process and make another selection. (This is where used book stores come in handy.)
Happy reading!
