Please recommend me some novels?

I'm a learner of English.So,I don't have vast vocabulary as native.I like to read novels.But I find it difficult for lacking of stock of words.But now with the help of my tutor I'm improving nicely.I find it easy to read novels by Agatha Christie.Her writing is so simple and so easy to read.PG Wodehouse,Rex Stout are also easy to read.So it would be great help for me if you suggest some authors or novels who or which are easy to read so that I can improve my English by read them.AND another thing,what about my English?If there is fault please point out.Aadvanced thanks for everybody.
