Ajaya: Roll of Dice is written by Anand Neelkantan, the book is about the great epic- Mahabharata.

This is not the regular story that we all have heard and read about Mahabharat. We have always comprehended these stories in black and white but here, it shows the grey side of the stories and the characters. This book talks from Dhuryodana's point of view and also talked about the characters who have been shadowed in the epic war, like Eklavya. The book doesn't describe Duryodhana as a mainstream villain like in other stories but here his rationality of the decision and the formation of the character is shown.

The author is not trying to justify his character but trying to humanise not only Duryodhana but all the characters and understand their voice that has been lowered all time. This story also showed the brutal reality of society and social class and injustice towards people during the war. 

heaven and Pandavas to hell, which made me think,  then why was he portrayed as a villain 

Here, he makes you question the stories and also make you think of what is actually DHARMA.
