From the author of the Guardian Herd series comes the final book in a thrilling fantasy adventure trilogy that SLJ called “perfect for fans of Erin Hunter’s Warriors series.”

Echofrost, Shysong, and all of Storm Herd are finally free, but their freedom came with a price. Sandwen Rider Rahkki Stormrunner has been captured by the Gorlan giants, who are quickly losing their patience with the Fifth Clan. With Rahkki in grave danger, Storm Herd must join forces with the humans they have long feared to save him.

And as sweeping monsoon rains threaten to ravage the region, enemies and friends, tame steeds and wild, will have to engage in one final battle to decide the fate of all three groups—the Sandwens, the giants, and the pegasi.

To save Rahkki and prevent a devastating war, unlikely heroes must rise. But who can be trusted when everyone is an enemy?

• Unlikely Alliances: Wild pegasi must join forces with their human enemies, the Sandwens, to have any hope of rescuing their friend from the Gorlan giants.
• Human and Animal Bonds: Follow the powerful connection between the pegasus Echofrost and the young rider Rahkki Stormrunner as their loyalty is tested in the face of war.
• Talking Animals: Dive into the rich culture of the Storm Herd, a society of intelligent, talking pegasi with their own laws, leaders, and legends, perfect for fans of animal fantasy.
• A World of Giants and Dragons: Explore a richly imagined fantasy world where fearsome giants aren’t what they seem and spit dragons roam the jungle.
