Stephen King!
The master of the craft!!
This book is the best thing happened to me! I liked the way he portrayed his memoir as well as the techniques of writing! From this memoir of craft I have learned a lot!
Especially about the adverbs! When we are starting with our writing journey, this book is helpful for us to know about the art of writing!
And according to me, On Writing is the basic course book we have to study for the art of writing.
