"The alchemist" - P. Coelho . That's nice and simple

Mark Haddon "The Curious Incident of the Dog in the Night-Time". It's teenager's autist story about his life. Very dramatic and very simple language. 

The shopaholic series is always my favourite!!

<em>Holes</em> by Louis Sachar

It'd be easier if you said what types of books you like and what your level is. If it's low you might want to try books for young teens. The print's bigger and the words are more basic but the stories can be enjoyable to read. It's a lot more enjoyable than choosing a difficult book which will be tiring to complete if your level is low.
