Every night, Aisling dreams of a different life. One night, a dragon appears. Aisling's life has been a fight for survival - surviving her mother's addictions, her negligent father, and a decade of homelessness. Working as a barista, hopeless and barely getting by, she relies heavily on a recurring dream to give her the peace and safety she lacks in her waking hours.

The peace is shattered when a dragon, injured and on the verge of death, falls from the sky and rewrites her fate.

Aisling neglects her reality and falls headfirst into the war-torn realm of her dream. There, she meets an elite group of bonded warriors and dragons designed to fight the Cruento, a faceless enemy intent on controlling women through fear and chaos. Aisling finally finds a sense of worth in the fight but teeters dangerously on the edge of insanity in her waking life.

What begins as an exciting nightly escape turns terrifyingly real when Aisling discovers she's a plane stepper - a soul able to walk worlds in her sleep. With each night that passes, Aisling's tether on her soul weakens, forcing her to fight against the empty void between worlds.

Aisling must choose where she belongs before her fracturing existence is irreparably destroyed, and time is not on her side.
