Most are winners of the Nebula and or Newberry prizes for literature - which generally means that they can be found in a local library. I will not bother to list all of the wonderful Heinlein novels and stories as they clearly have many champions, though I will plug the anthology "The Past through Tomorrow" which hooked me at age nine and started a life long passion for reading.
The Chronicles of Prydain - wonderful series based around Welsh Mythology, basis of Disney's "The Black Cauldron".

Ursula LeGuin
The Earthsea Trilogy - I cannot recommend this series enough. If your children had any interest in the "Harry Potter" series this is a must read.
