Edrin Voss grew up in Hollowreach, a tin-mining town pressed against the treeline of the Ashwood, a forest the locals knew to stay out of after dark. His mother, Maret Voss, ran the assay office. His best friend was Corin Dace, the mine foreman's son. They were inseparable: sparring with pickaxe handles behind the smelter, sneaking to the forest edge on dares, swearing they'd leave Hollowreach together and never look back.
When Corin discovered an unmarked silver vein running beneath the Ashwood's cursed soil, he needed someone to help him stake a private claim before the mining company found out. Edrin said no. Corin took him into the forest anyway and put a knife in his back at the mouth of the vein, burying him in the loose shale so no one would ask questions.
Edrin was dead for nine days.
On the tenth day, he pulled himself out of the ground, grey-skinned and dirt-caked, standing in a forest clearing with no memory of the blade but a perfect memory of Corin's face. Beside him stood something that looked exactly like him: translucent, hollow-eyed, still wearing the wound. His mother took him in without questions. The town healer, Silla Ren, confirmed what she could: his heart beat, but slowly. His blood ran, but cold. Whatever brought him back left the door open, and the echo walked through it.
Edrin left Hollowreach because the echo is growing and he's running out of time to understand what it wants, or what happens when it finishes becoming him. He doesn't care about Corin. He doesn't want revenge. He wants to know what he is now, and whether the thing standing next to him is a ghost, a warning, or a replacement.
