This arc is about how the clans were created and came to be.
Book 1: The Sun Trail
For many moons, a tribe of cats have lived peacefully near the top of a mountain. But prey is scarce and season are harsh—and their leader fears they will not survive. When a mysterious vision reveals a land filled with food and water, a group of brave young cats set off in search of a better home. But great danger awaits them. In this unfamiliar world, faced with loners and fierce rogues all vying for territory and power, the travelling cats must find a new way to live side by side—or risk tearing one another apart.
Book 2: Thunder Rising
The mountain cats followed the sun trail to a new territory, convinced that in a land with more prey, their lives would be free from strife. But while no cat has gone hungry, tensions are rising—and the once firmly united group has split in two. Caught in the middle is a young cat named Thunder. Orphaned after his father, Clear Sky, rejected him, Thunder has thrived under Gray Wing's watchful eye. But Thunder cannot escape the memory or hurt of his father's rejection. When a devastating fire rips through the forest, Thunder's natural abilities are put to the test. Impressed, Clear Sky invites Thunder to join him. But allegiances borne over time can be stronger than blood ties, and Thunder is forced to decide if he is with his father—or against him.
Book 3: The First Battle
Since fleeing from Clear Sky's camp in the forest, Thunder has safely returned to settle on the moor with Gray Wing. But the rivalries that have plagued the cats for moons are growing stronger. Gray Wing still believes there is a way for both groups to live in peace, while Clear Sky insists that harsh rules and divided territories are the only hope for the future. What started as a misunderstanding between two brothers has spread far and wide—and now every mountain cat, rogue, and kittypet who settles in the forest will be forced to pick a side.
Book 4: The Blazing Star
In the aftermath of the first great battle, the grounds of the four trees have been stained with blood and every cat has lost denmates and kin. Now, guided by the spirits of the fallen, the cats from the mountains must figure out how to move on. Though each group has sworn to a truce, simply keeping the peace may not guarantee their survival. Having lost Turtle Tail and given up his role as leader to Thunder, Gray Wing is no longer sure where he belongs. Clear Sky is losing his grip on the forest cats to a dangerous one-eyed rogue. And worst of all, a mysterious, deadly disease threatens to strike deep into the heart of both camps—keeping tensions simmering close to the surface. Only one thing can save them: they must seek the Blazing Star. . .
Book 5: A Forest Divided
Leaf-bare has fallen once more, threatening all cats with hunger and cold. Meanwhile, the message from the spirit-cats remains the same: in order to survive, they must grow and spread like the Blazing Star. And they must hurry. Clear Sky is certain that the only way forward is for all cats to band together again, but few are willing to ally with him—and Gray Wing and Thunder can barely look him in the eyes. Tall Shadow is determined to establish a new camp in the pine forest. River Ripple is content near the water. And Wind Runner has made her own home on the moor. The time has now come for all cats to decide where they will live—and where their allegiances truly lie.
Book 6: Path of Stars
After moons of deliberation and strife, the forest cats have settled into five camps, following the spirit cats' advice to spread out like the petals of the Blazing Star. But now the dangerous rogue Slash has kidnapped Star Flower and made demands for prey that the forest cats cannot afford to meet. Clear Sky is desperate to save his mate and the kits she carries, but he cannot do it alone. To have any hope of defeating Slash, Clear Sky must join with the other groups, led by Tall Shadow, Wind Runner, Thunder, and River Ripple. The other leaders are reluctant to risk helping Clear Sky, but as Slash's rogues grow more brazen and their attacks more vicious, all five groups will have to work together if their new way of life is to survive.
