Riftborne (Trilogía Esprithean, 1)

Decades after a rebellion swept across the island of Sídhe, Fia Riftborne has learned three essential lessons for survival: keep your head down, stay out of the spotlight, and avoid the Sídhe Guard at all costs. But it's not that easy: Fia harbors a secret power that, if discovered, would put her in grave danger. And when a simple errand goes wrong and unleashes it, Fia knows she can no longer hide. Instead of the immediate punishment she expected, General Laryk Ashford offers her an ultimatum: join the Sídhe Guard… or face execution. Soon, Fia faces another impossible choice: surrender to the chaos within and risk destroying everything she loves, or become a weapon in the hands of those who took everything from her… including the seductive Ashford, who begins to take over her every thought.
