The Origin of Pietas — Kayelle Allen

Love shatters even the unbreakable.

A story of military genetic engineering in a dystopian world. Listed as scifi - but it's the truth--if we let it happen.

Two enemy warriors: one human, one immortal.
Different in belief, alike in spirit, marooned together on an alien world.

Imprisoned and in isolation over a year without food or water, the immortal Pietas survives. Though broken in body, his intellect and will are intact, thanks to Six, the special ops warrior who captured him, but kept him sane.
The warrior had no hand in his deprivation and, like Pietas, was betrayed by his own kind. When Pietas is abandoned on an alien world with nothing but his honor--and Six--he must find and rejoin other immortal exiles. After centuries of war, Pietas detests humans and kills them on sight, but he is too damaged to continue on his own. Though he despises needing help, he allows Six to nurture and restore him to full strength, and then accompany him.
As they cross the planet together on foot, the immortal begins to wonder if he has found his first human friend, or if Six is loyal only because Pietas could keep the others from tearing him to shreds. This human will either be his closest living friend, or the one whose betrayal will trigger all-out vengeance by the most powerful immortal ever born.

Immortal. Warrior. Outcasts. Traitors took everything. Except their honor.
