The Bone Raiders (The Rakada, #1)

This epic fantasy follows the story of the Rakada, a fearsome band known as the Bone Raiders, due to their charming habit of wearing the bones of those they kill on their armour. But being a raider is tough these days, especially when the High Chieftain is trying to wipe out you and your kind. When Sayana, a young Rakada scout, finds herself face-to-face with a fire-breathing lizard of legend during a raid-gone-wrong, she comes up with an audacious plan to save the Rakada and preserve their way of life. A plan that involves convincing the lizard to let her ride it.
