Depends on your personality, and age. Obert Skye writes YA fantasy. I read his books, and I liked them, they aren't the best, but they aren't terrible. Although with his Leven Thumps series, the first book is terribly written, if you can make it past that though, the rest are much better.
There will be a new series by Obert Skye. I am not sure if Leven will be in it or not, but the series is going to be called Geth and the Return of the Lithens. So no, there will not be a Leven Thumps the 6th.
