I just finished the Septimus Heap series by  Angie Sage.  Or what is finished of the  series.  So far there are 4 books.  They go in this order: Magyk, Flyte, Physik, Queste.  If you like magic and wizards I think you will enjoy this series.  It reminds me a lot of the Harry Potter books.  I like to read books that have been written for a younger audience.  Then you can avoid any language or innuendos that you aren’t looking for.  This series has wizards, a castle, a princess, dragons and all sorts of other creatures.  You have of course two sides Light (good) & dark (bad).  There are two main characters Princess Jenna and Septimus Heap.  There are also a lot of other Characters but for the most part the stories are based around these two characters.  I don’t want to tell you too much about the books because I don’t want to ruin them for you.
