Young Adult's literature is still as important today as it was yesterday for a civilized and clean society, the prosperity of the country, and the future. Young Adult's books should use relatively simple language. The expression's tone and style should be such that they read them with joy, become interested in them, and feel joy thereafter. "ThagoN ka Badshaah (King of thugs)" is such a wonderful and interesting novel on the life history of famous Thug of Asian sub-continent 'Ameer Ali Thug' and written by Urdu laureate Dr. Abdul Waheed.
