Gods will fall.

Calidan Darkheart is an Imperator. A hunter of monsters and men. He has been broken and reforged time and time again, becoming the sharp blade of the Emperor’s will.
But no more.

Now he will become vengeance. He will become a hunter not just of monsters, but of the very gods themselves.
Because only one thing in this world
Getting his cat back.

And if gods need to die to allow that to happen?
So be it.

This is not a redemption. It's a reckoning.
Calidan Darkheart is going to war.


The epic conclusion to David Oliver’s The Great Hearts Saga — brutal, heartfelt, and unforgettable. For fans who have walked with Calidan since the beginning, this is the final descent into darkness.

I found this series in 2025 and so glad the final installment came out. It is amazing that the author didn’t have a grand plan for the series when he started as things Calidan said in the first book resonated at the end. I enjoyed the escape from reality.
