Summary

The third and final book in The Nightfall Saga, the thrilling and action-packed epic fantasy series set in the world of The Demon Cycle, from Sunday Times bestselling author Peter V. Brett

"Heart-wrenching, smart, and modern … The Desert Prince has set a new standard for fantasy."–Wesley Chu, author of The War Arts Saga

He is known as The Prince of Lies. The Father of Demons. He is Alagai Ka, the Demon King.

Though humanity won a hard-fought victory in its war against demonkind, the Demon King has escaped in search of a new queen to restart his dark hive, and has found signs of one on a distant shore.

But pursuing him are humanity's best hopes: Olive Paper and Darin Bales, whose legendary parents brought demonkind low once before. Olive and Darin will not rest until the demons are defeated, and so relentless is their hunt that they have followed Alagai Ka across the sea to a strange new land.

There they discover a culture unlike any they have never known, where demons live alongside humans as servants and companions. And there they meet the demon's masters–including a seductive prince who is drawn to Olive – who seem unable or unwilling to understand the danger they are in.

Because no human is safe from the Demon King's thirst for war – and every human must join the battle against his kingdom of death.

I was worried this would be a rehash of the first series but the author managed to take the same concepts to some interesting places.

The story evolves into interesting places

I finished this and was left thinking this was more of a bridging novel rather than an epic stories end. The characters we've grown to love were left behind and a whole new cast of people we had no love for were introduced in the final novel. This book reeks of a story intent on launching another series of books in the future.
I finished think more disappointed than satisfied.
unfortunately it was the worst book in the entire series.

The finale to an epic tale that leaves most of the characters behind.

I loved following the characters and seeing them grow up but this book had a lot of gaps and inconsistencies which I didn’t expect from the author and the characters. Good to end the series though.

Good conclusion but weakest book of the series

It definitely felt pretty experimental and honestly hats off for it. But, there is a new host of characters and I honestly didnt care for any of them I kept hoping the old characters would make a return. alas no. unfortunately for me it's the weakest book of the whole series including demon cycle.

I hope we get another series.

I love this series but.

It was a great wrapping up of a story. The three points of view were awesome. The narrator gave each point of view a whole new element and brought characters to life.

Brilliant
