The only person who ever showed her sincere warmth was her older sister, the Second Princess Aria. But that fragile trust shattered in the most merciless way.

A princess betrayed, and the deadliest slave knight who once ended her life. Bound by poison and chains, their dangerous and beautiful master, servant romance now begins.s.
