Book 1

Eyrie

by K. Vale Nagle

Published 24 March 2019

Gryphons, murder, war, and tasty fish!

Zeph is the craftiest gryphon in his pride. Living in the untamed wilds, he hunts in the shadow of the massive sky-cities of the opinici, evolved gryphon cousins. His taste for parrots leads him to a murder scene and a blood-stained notebook—a notebook the opinici will do anything to get back before he unravels the mystery at the heart of the eyrie.

Kia is a serious opinicus scholar with no time for gryphons, but when her best friend goes missing and only a strange notebook holds a clue of his whereabouts, she’ll even team up with an uncivilized parrot hunter to get him back.

When the peace that has held for so long is shattered, they’ll find themselves mixed up with curious songbird scholars, legendary cranes, murderous owl gryphons, mad scientists, and the cunning peafowl who rules them all.

Will Zeph make the sacrifices necessary to protect the life he’s always known, or will both their worlds crumble to ash?

Ashen Weald

by K. Vale Nagle

Published 19 June 2019

A world on fire. A gryphon army. A mysterious sickness.

For years, Satra rotted in the dungeon depths while her kin were forced to wage wars to keep her safe. Now the eyrie is ash and she controls the largest army the continent has ever seen. As her opinicus enemies plot and scheme, she sets her sights on the Crackling Sea, where the last of her kin are held hostage.

The snowy taiga gryphon Younce is one step away from being banished. Sent to investigate the frozen catacombs on the southern coast, he discovers dead gryphons, violent wildlife, and a hidden camp.

After an infected gryphon leads him to a city of rafts and sea monsters, he begins to suspect that something more may be going on. Something bigger than just the taiga and coast. Something with terrible implications.

While Satra squares off against treacherous taiga gryphons, vicious peafowl opinici, and mad scientists to save her kin before they’re executed, Younce uncovers a plot that goes far beyond sick gryphons. Will his warning reach Satra in time, or is it already too late?

Ashen Weald is a full-length fantasy adventure full of gryphons, monsters, war, and wet fur.
