The latest book I have read was "And then there were none-- by Agatha Christie"
However I would not recommend it to you as you are still Beginner at English, but I would like to suggest you few good short stories book which are certainly enjoyable and helpful for getting hang of English.
The names of the books are as follows:
1. Charlie and the Chocolate Factory- Roald Dahl
2. Kiss Kiss- Roald Dhal.
3. Eggs, Beans and Crumpets--P. G. Wodehouse.
Hope this helps.
