Mr Iyer Goes To War by Ryan Lobo
Dispatched to a home in the sacred city of Varanasi, Lalgudi Iyer spends his days immersed in scripture. When an accident leaves him with concussion, he receives a vision of his past incarnation - he was the mythological warrior Bhima, sent from the heavens to destroy evil.
 
Vikramaditya Veergatha Book 1 - The Guardians of the Halahala by Shatrujeet Nath
The deadly Halahala, the all-devouring poison churned from the depths of the White Lake by the devas and asuras, was swallowed by Shiva to save the universe from extinction.
But was the Halahala truly destroyed?
A small portion still remains – a weapon powerful enough to guarantee victory to whoever possesses it. And both asuras and devas, locked in battle for supremacy, will stop at nothing to claim it.
 
The Krishna Key Paperback by Ashwin Sanghi
Five thousand years ago, there came to earth a magical being called Krishna, who brought about innumerable miracles for the good of mankind. Humanity despaired of its fate if the Blue God were to die but was reassured that he would return in a fresh avatar when needed in the eventual Dark Age - the Kaliyug.
In modern times, a poor little rich boy grows up believing that he is that final avatar.
Only, he is a serial killer.
In this heart stopping tale, the arrival of a murderer who executes his gruesome and brilliantly thought-out schemes in the name of God is the first clue to a sinister conspiracy to expose an ancient secret - Krishna’s priceless legacy to mankind.
