The Star Wars Universe has been given new life in the myriad novels that have been published. Set during the films, before the films and after the films a lot of has happened to the familiar cast of characters since Return of the Jedi finished the movie saga.
Controversy has been courted by these books when they killed Chewbacca, and Leia and Han's youngest son Anakin. Luke married a Sith assassin who was trying to kill him, and various members of the Solo family have turned to the dark side and come back.
But any fan of the movies will enjoy the books. It is good that Lucas is happy to allow the universe he created to grow and evolve. This is not to say that he hasn't got a firm hand guiding the ship, but with publishing these novels the adventures continue and it is fun to revisit a group of characters who feel like old friends.
