After being run out of Boneville, the three Bone cousins - Fone Bone, Phoney Bone, and Smiley Bone - are separated and lost in a vast, uncharted desert. One by one, they find their way into a deep, forested valley filled with wonderful and terrifying creatures. Eventually, the cousins are reunited at a farmstead run by tough Gran'Ma Ben and her spirited granddaughter, Thorn. But little do the Bones know, there are dark forces conspiring against them and their adventures are only just beginning!

Fone Bone and his cousins plan to return home after visiting the village of Barrelhaven with Thorn and Gran'ma Ben. But Phoney risks everything on one last get-rich-quick scheme for the town's annual Great Cow Race. As usual, Phoney's plans go disastrously awry, and Boneville seems further away than ever. Meanwhile, ominous signs indicate that a war is brewing, and Fone finds himself helping his friends defend their valley from a formidable enemy.

In "Eyes of the Storm," volume three of the nine-book BONE saga, Lucius, Smiley, and Phoney survive an attack by the rat creatures and return safely to Lucius' tavern in Barrelhaven. Phoney, desperate to win a bet with Lucius, stokes the townspeople's fear of dragons and boasts that he is a professional dragonslayer.

Fone Bone confronts a host of dangers in Book 4 of the BONE saga, "The Dragonslayer". He and Gran'ma Ben and Thorn have a terrifying encounter with Kingdok, ruler of the rat creatures. The Hooded One is inciting his army to full-scale war. Someone is continuing to haunt Thorn in her dreams. And then wise Gran'ma Ben disappears.

To make matters worse, Phoney Bone has hoodwinked the townspeople into believing that he is a mighty dragonslayer. When he actually does catch the Red Dragon — much to his surprise — he must face up to his promise: to slay the dragon at sunrise.

Fone and Smiley Bone strike out into the wilderness to return a lost rat creature cub to the mountains. It doesn't take long before they run smack into Rock Jaw, "Master of the Eastern Border," an enormous mountain lion with a none-too-friendly disposition. Life gets even more complicated when they befriend a group of baby animals who are being orphaned by rat creature attacks. Everything comes to a head in an earth-shattering clash between Rock Jaw and Kingdok, the leader of the rat creatures.

The thrilling BONE saga continues in book six. As war spreads through the valley, the Bone cousins join Gran'ma Ben and Lucius at Old Man's Cave to make a stand against the rat creatures.

But not everything goes as planned. By the end of the book, Phoney Bone is strapped to a stone altar and about to be sacrificed; Thorn is lying lifeless nearby; and the rumblings of an earthquake suggest that the Lord of the Locusts is about to be released. Fone and Smiley Bone must do something drastic to save their friends.<

A long-dormant volcano explodes, blacking out the sun, mowing down trees, and filling the land with soot and ash. The Lord of the Locusts is released with the eruption. Against this apocalyptic backdrop, the Bone cousins along with Thorn and Gran'ma Ben struggle to reach safe haven in the city of Atheia. Meanwhile, Lucius Downs lies severely wounded and trapped with the villagers in the camp at Old Man's Cave.
