Book 3: Legend of the Forest Beast

Kaye’s father is in danger!

The young knight, Kaye, and his friends Reggie and Beau enter Eldridge in search of the only man who can save Kaye's father. During their journey, they encounter and make a powerful enemy of Baron Thomas—the self-proclaimed heir to the throne of Eldridge—who also has his sights set on ruling the country of Knox. Together, the boys dodge the baron’s henchmen and race against time to stop an assassination that would plunge the two kingdoms into war in this exciting conclusion to the series.


"This set of books just gets better and better. Yes, it’s a non-stop adventure, packed full of nasty barons and battling knights. But it’s also a story which is strongly-themed and where the bond between the characters is highly prized." —The Wishing Shelf Awards Book Review

“Books of adventure and challenge that still offer an emotional component are hard to come by for middle grade boys—yet Don M. Winn hits the mark dead center with The Eldridge Conspiracy.”
