The Soulbound Saga Books in Order

The Soulbound Saga is Matharu's move into adult fantasy, and it feels a little heavier from the start. The series follows Jai, a young man held as a royal hostage in the Sabine Court after his father Rohan led a failed rebellion and was executed. Jai grows up close to power, but never safe inside it.

His dream is simple at first: survive, get free, and return to his people.

That changes when the Sabine emperor's heir is betrothed to Princess Erica of the Dansk Kingdom. Her dowry includes dragons, creatures whose true power is guarded by Dansk royalty. Soulbonding is the secret at the heart of the series. A rider and dragon do not just share a saddle; they share strength, danger, and a link that changes what each can become.

When the court falls into chaos, Jai escapes with Frida, a Dansk handmaiden, and a stolen hatchling named Winter. From there, Dragon Rider becomes a flight story, a training story, and a revenge story all at once. Jai has to learn cultivation magic step by step, not by waving a wand or discovering one perfect trick. His progress is hard won, and Winter is growing too.

The setting widens in The Tainted Khan, as Jai reaches the Great Steppe and discovers that returning to his own people is not as simple as claiming a birthright. He meets the Tainted, learns how much he doesn't know about steppe politics, and faces the fact that his uncle may not want to give up power. At the same time, the Sabine Empire and its Gryphon Guard keep pressing against the tribes.

This is dragon fantasy with a progression engine under the hood.

The series mixes creature bonds, imperial politics, clan loyalties, and battlefield pressure. Jai wants freedom for the Kidara, but the books are clear that leadership is messy. Every alliance has a cost. Every increase in power brings a new problem. If Summoner is Matharu's magic-school adventure, The Soulbound Saga is his slower, tougher look at exile, revenge, and what it takes to become the person others need you to be.
