“This is a fast moving tale about two sisters, one a blind but gifted psychic (Annie) and the other a very well-trained spy (Fia). Neither had much of a choice--they have be abandoned by their family, and the "school" that they live at requires them to use their abilities to promote the unknown goals of the institution. As what is demanded of them becomes more dangerous and suspect, Fia uses her training to find a way out. There's a lot of pulse pounding action-- this book is a true psychological thriller that might surprise the fan's of the author's Paranormalcy series. This book has an edge, and I for one really enjoyed it.
