I thought this was a fantastic start to what is sure to be a thrilling series! The story flowed with a steady pace and the twist of the half-breeds really peaked my interest. My only negative is I wish it were longer. Andrew Wehrlen was a good narrator, easy to understand with identifiably different character voices. I am eager to read/listen to more in this series especially to learn more about Penelope. I was given this free review copy audiobook at my request and have voluntarily left this review.
