River's End vol. I
Ignorance is a blade. Knowledge forms its hilt.
Rose's royal sister entrusts her with a message meant to save Grenswa, a watery world of artists and musicians that she adores. Two centuries ago, they were nearly wiped out, but no longer trust outsiders. With danger on the way, she must restore their faith in her kind, but around every corner lurks another secret waiting to show her just how ignorant she is.
