In the midst of a dangerous raid, Tassia, an elite soldier from the Wheat Sky empire, rescues Sam, a wandering nomad, from inside the compound of a lunatic enchantress. While Sam serves his debt to Wheat Sky, he and Tassia grow closer as they tend her garden together. Sam falls in love wholly and immediately, but Tassia's feelings bloom slowly, and her reluctance to commit to Sam is further complicated by her discovery of his true identity. As they attempt to secure peace between their rival kingdoms, Tassia and Sam find that their relationship and their very lives are in jeopardy.
