+<p>Welcome to Stefan's Database of Favorite Books and Authors!<br>
+ <br>
+To be honest I am not really a book kind of guy. Why read a book when you can just watch instead you feel me? Nevertheless I do prefer to read fictional fantasy kind of books such as that of mainly the Harry Potter and Percy Jackson books. With that in mind I personally look up to Rick Riordan because J.K Rowling has a bunch of controversies while Rick Riordan just seems like a down to earth kind of guy. </p>
