I again use both first name and surname for this alphabet. Khushwant Singh is in K because S is such a common alphabet that there is a big war going on there already.
Yes, choosing authors for S is difficult because I am spoilt for choice! For K today I have 4 authors yet again that I had to feature, all of them with very diverse books and views yet all doing extremely well in their writing.
If writing stirs our passion then it has done its job is the best example of their writing.
So go ahead and tell me who do you like best?
