Heartless Sky [Zodiac Academy Series, Book 7] - Caroline Peckham, Susanne Valenti

The winds of fate are shifting, and it finally seems like they’ve been twisted in our favor. On the run and cast out from society, we’ve been forced to hide from the madman who stole our throne. But as more secrets come to light, and my sister and I work harder than ever before to reach our potential and claim our birthright, the end is finally drawing closer. There is no turning from this path now.
