Some good novels for improving english.
Hey there!
I would suggest you to go for those novels which have normal english vocabulary and sentence formation.Don't start from Shakespeare and Orwell.Instead you can read some Indian novels and novels with beginner english ,not advanced one.
You can read any book as per your interest.If you like fiction go for it.If Self-help and non - fiction genres make you feel good,read them.
