Piaffe (The Legacy of Three, #1)

Five years after his forced conscription, Eldrenji Sorenne and his insignis, Davyn, are present to witness the Emendati forces receiving Jaedyn Myfala into their ranks. As the squad's medic, it's his responsibility to ensure the already wounded man makes it to the training facility in one piece.

Jaedyn is a disenfranchised orphan with nothing to his name but that--a name, and a stone as smeared with blood as his memories. He's watched his sire die twice in the span of a decade, and he's determined to make someone pay. Ethos and respect have intrinsic value that those around him seem only ready and willing to exploit. Conscription and the consensus that comes with it are all he has left. The prospect of an insignis means he won't be alone; at least there'd be someone watching his back. It's the best he could hope for.

But Jaedyn presents a danger: to himself and Modalynde, his insignis; to Eldrenji and his well hidden secrets; to the forces nearest him, regardless of their prowess or skill. He has vengeance on his mind, a strange amulet resting on his chest, and five kinds of trouble on his heels.

About The Legacy of Three:
When the paen revolted, they toppled mardonken civilization from its pinnacle back into an agrarian struggle for survival. They destroyed all but a remnant of the powerful summa who once served the three races as immortal leaders.

Though generations have passed since the Revolt laid waste to half a continent's ecosystem, left every metropolis in crumbling, skeletal ruins, and extinguished the flame of Aedis Idolon's bloodline, Alea's thirst for summa blood is not yet quenched. In order to find the final three and free the Paen forever from the oppressive rule of those who would control the endless line of ancestral knowledge, Alea must hunt down those mardonken who hold the keys to awakening them.

The mardonken and insigni sworn to guard the legati, the last of the summa, will stop at nothing to ensure their preservation.
No cost too great, no sacrifice too large, no wound too deep.
