That Which Devours - Evolve. A LitRPG Adventure (en Inglés) - Jer Patch

Evolution is within reach, if only Alex earns it.

Alex is a shadowstalker, the darkness is her battleground and the fallen her food. After the raid destroyed the Forgers cloning facility, new doors open to her, but villains from the past arise. Ancient powers stir, and the world trembles.

When a distant portal offers the only hope for a reunion with Dengu, Alex and her allies are forced into the Labyrinth-where academies teach power, beasts stand guard, and dangerous bosses demand a price paid in blood.

Every floor conquered and mini boss slain brings her closer to ranking up, yet the ticking clock of the outside war threatens to turn her victories into ashes. As her broken build leads her astray, Alex must fuse the crystal song she knows with the rune craft she is just learning, forming something new.

Failure means Kabi's world falls, but success might change her forever.
