Crown of Ice and Fire

Seline is intimately familiar with blood. She sees it daily tending wounds and spills it nightly with the same hands. After witnessing her parents' deaths at age six, she learned a brutal truth: life is a vicious game. Her only sanctuary was among thieves and assassins, where she became the ultimate authority in a life tightly controlled and ruthlessly commanded.
Her rigid calculus of survival shatters the night Raiden arrives. A being whose terrifying, rare power commands absolute horror, Raiden is undone by Seline, who is absolutely immune to his every psychic touch. She is the only thing he cannot control, the only person who doesn't fear him. When she slips his grasp, his immediate reaction is obsession. Unwilling to lose the one person who challenges his supremacy, Raiden kidnaps the only thing she has left: her brother.
This forces Seline out of the familiar grime and into the whispered myths: a hidden world where magic is real and the rules are rewritten. For the first time since childhood, Seline is powerless, and Raiden is desperate. He needs to study her, this fragile human who offers no response to his immortality. In a reality where she is the weakest being considered lower than dirt, she must survive the fantastical new reality, or lose her brother forever to the dark obsession of the being she cannot break.
