Eris Taeresin, third daughter to the king, has searched the massive palace garden for a flower that will let her learn the secret language of flowers. Each day the Mistress of Flowers finds some reason to refuse, all while her sisters found theirs easily.
When Eris finds a strange flower and meets Terran, a handsome young gardener, she discovers the Mistress of Flowers might be a flower mage who intends to use the garden in a plot against the kingdom. Eris soon learns the threat against the kingdom is deeper than she suspected. She might be the only one able to save it from destruction, if only she can learn to use her own magic in time.
