Luckily, my estranged dad has pulled some strings for me, my friends, and, of course—my guys. We may be spies in training at Darkside, the shadow organization my dad’s a part of, but that doesn’t mean I’m any freer than I was at the Academy. While my friends are off on dangerous missions? I’m stuck here like a princess in a castle. What’s worse—sub-class and half-monsters are going missing all over the world. While I’m busy training and falling in love, the monster world is falling apart. And with everything we’ve been through, I’m not taking this lying down. Kings of monsters, sibling rivalries, conflicts over my heart—we may have left the Academy, but there’s so much more trouble to be had.
