The Mora by M.R. Graham

A murder. A betrayal. A war.

Jadwiga Dąbrowska, dream-eater, wakes from her own murder in a bizarre mirror world, chained body and soul to a terrible being, the Shadow’s Face. With no choice but to obey the Shadow, she must contend with forces outside her understanding, fighting in a war that will never end.

She can’t be sure that her freedom was a fair price for her life.

Kim Reed has spent years searching for a lost friend, but her search is interrupted by war. An ancient wizards’ Circle is reaching for power, backed by black magic. With her own magic atrophied and her past making her an object of suspicion, she is not ready for politics, war, or spies manipulating her dreams.

All she wants is her friend back, but there are Shadows standing in her way.
