SSS: Rise of the Beastmistress

Serena Sterling transmigrates into a novel as the doomed fifth princess, a mere cannon fodder fated to die in the first chapter. To defy fate, she saves the future Archfiend, Cassius. Hiding her power, she levels up and tames tiger Magnus and phoenix Valerian. Rising to a Tier-10 tamer with three SSS beasts, she crushes plots, defeats villains, and embraces darkness to rule, turning Gloryhold into Shadowhold.
