Tatiana and the Shadowtongue

Tatiana and the Shadowtongue
Tatiana, a resilient half-demon/half-human orphan, possesses a rare ability to speak Shadowtongue - the native language of demons. Taken in by a human Duke who seeks to exploit her gift, Tatiana endures unspeakable abuse from the Duke's family. Nevertheless, she perseveres as an interpreter between the demon and human kingdoms, hoping to bridge the divide and earn her family's love.
Her dedication proves futile when the Duke uses her as a political pawn, leading to her untimely demise. But just as Tatiana accepts her fate, she inexplicably awakens a year after her death. Armed with knowledge of the Duke's nefarious deals, Tatiana escapes to the Demon High Court and offers her services to the enigmatic Demon King Luther in exchange for protection.
Initially skeptical, Luther is intrigued by Tatiana's bravery and her fluency in Shadowtongue. As they work together, Tatiana discovers a surprising warmth beneath the Demon King's icy exterior. But with their respective worlds at odds and enemies lurking in the shadows, will their newfound bond be enough to overcome the forces working against them?
