Dawn of Vengeance

Story

Arsinoe knows a few things about redos. Her first three lives all followed the same tragic script: born the scorned daughter of an enslaved queen, married to a crown prince as charming as he is cruel, and driven to death by the very man she trusted. But in her fourth, Arsinoe refuses to play the doomed princess. Determined to claim her own destiny, she forms an unexpected alliance with Walter Heibergh, the kingdom’s most formidable commander — one powerful enough to change fate itself.
