The Demon King

By Peter V. Brett

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 New York 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.

A must read

Amazing book. I swear Peter v Brett never disappoints. Wonderful world building and characters you truly care for. Was stressed out when book two ended on a cliff hanger. Was ready to dive into this book to find out what happens next. Delving into this new world that Darin and Olive find themselves. To see how these two young people grown and thrive in a world so different from the one they know. Darin is my favorite and I just want to keep him in my pocket and keep him safe. I think I care more about him than I did his father in his books. I know this is the last of this series, but I truly want more of Darin and his story. He’s such an amazing character. I’m almost sad there won’t be another book. Hopefully there will be some short stories as he did with the prior series. Exploring new people, new way of living, new view of the demons they have been hunting, and if this is a world they can live in, I don’t need therapy after this book as I did with book two, but I will have a bit of book hangover. Such an amazing series is rare. I wish more u derstood how amazing of a writer this is.
