Dragon fire no longer blisters the skies over Penterra, but inside the lavish palace, life is still perilous – especially for Tamsyn. Raised in the glittering court alongside the princesses, it's her duty to be punished for their misdeeds. Treated as part of the royal family but also as the lowliest servant, Tamsyn fits nowhere. So when she is tasked with the ultimate sacrifice of pretending to be one of the true royal princesses and marry Fell, the Beast of the Borderlands, son to the great dragon slayer, Tamsyn accepts her fate even if it means tricking the deadly warrior.

The wedding night begins with unexpected passion, but ends in near violence when her trickery is exposed. Rather than start a war, Fell accepts Tamsyn as his bride … but Tamsyn isn’t what she seems. She harbours dark secrets, secrets buried so deep even she doesn’t know they exist.

For Tamsyn is more than the false wife of a man who now sees her as his enemy. And when those secrets emerge, they will ignite a flame bright enough to burn the entire kingdom to the bone.
