The Untethered Demon — J. Stone

Astrid has seen better days. A demon and assassin, Astrid invoked a spell from a forbidden book in an attempt to kill her latest target. She failed, and worse, Astrid's invocation split her into two bodies, only one of whom survived the bumbled job. Crippled by her own magic, Astrid sets out to locate a necromancer, pilfer a resurrection spell, and revive herself. Peril abounds in Nabiria though, and even the simplest tasks can prove deadly. Restoring what Astrid lost will not be simple.
