When Charlotte Mirran is kidnapped by humans claiming to be a secondary breed called Chivals, she is not sure what to think. Following her new friends, Rowan and Arquette, she learns of their secret society, their mission to keep their breed secret, and the unexpected drama of her own past. Heart of Grandeur, a drug that allows the user to take any form imaginable, is an addictive substance the Chivals seem to thrive off of, and although it could free her from the monotony of the simple life she has created, Charlotte learns it has influenced more than she could imagine.
