Have you finished reading the Caster Chronicles by co-authors, Kami Garcia and TBF author, Margaret Stohl? If not, start with the first book, Beautiful Creatures. Here's my review. After reading Beautiful Creatures, the next book is Beautiful Darkness, (in between is e-novella, Dream Dark) third book is Beautiful Chaos and the fourth and final book is Beautiful Redemption.
Mourning about the end of the Caster Chronicles? There's good news! Margaret Stohl has a new series called Icons. The first book will be released on May 7th, just in time for TBF! Yay!
P.S.--More good news! Kami Garcia also has a new series called Legion. The first, Unbreakable, is expected to be out October 1st. So many books to look forward to this year!
