Princess Mancella Cliff is heir to a brutal kingdom ruled by her ruthless father. Her terrifying magic allows her to summon animals—but only after killing them with her own hands. Every use of her power reminds her of the cruelty she's been raised to perpetuate.

Meanwhile, Silver, a charming thief, is recruited for an impossible heist: infiltrate the royal palace, gain Mancella's trust, and steal from the king. What begins as deception slowly becomes something far more dangerous as both discover that the greatest threat to the kingdom isn't each other.
