Fatebound (en Inglés) - Amelia Cole

The Druadan Legacy series is an adult romance set on a distant Earth, where centuries of rising seas have transformed the land masses into a scattering of islands.

In a world where the sea has claimed most of the land, the once-mighty druadan faces extinction. Genetically engineered for ancient wars, these loyal horses are telepathically bonded to a single rider. Centuries after the final battle, their numbers are dwindling, and the few remaining are kept in stations and used for demonstrations only.

*******************************************

Venovia is gone.

The air's too toxic to breathe. ITM took everything-our cities, our homes, our future. What's left of us fled to the sea on ships, waiting for a salvation that won't come.

I thought it was over, and all I had left was Oriana, my riders, and the weight of everything we failed to save.

Then Marshal told me that my father was alive and might know a way to save us.

He's on Canna Canna, a remote island no one talks about. Where the air is clean, and tribes of druadan riders have ruled and clashed for centuries.

There, I learn a druadan's bond holds untapped power that could tip the odds in our favor. But nothing comes without a cost, and to unlock it, my riders and I must survive a gauntlet of brutal trials. Each one will test our strength, our loyalty, and above all, the love that binds us.

This is our last chance. If we fail, Venovia falls... and the rest of the world won't be far behind.
