Beyond the Veil (Zodiac Academy, Book 8.5) by Caroline Peckham

The stars called us.
The Veil closed at our backs.
And now death holds us in its clutches.

We were torn from life before our time, a Savage King, his queen, a betrayed son, a wronged brother, a scorned wife and so many more. We watch those we left behind as they struggle against the grip of the stars, the answers to so many of their questions within our grasp and yet out of their reach.
But what if we could find a way to answer their pleas? What if we could find a way to help them from this side of the divide? And what price would such a thing come at?

***This is a bridging book which takes place beyond The Veil (in the land of the dead) during the events of book 8 in the Zodiac Academy series. It should be read after book 8 to avoid spoilers for that book and holds the answer to what takes place for the characters who are held within the clutches of death by this point in the story, as well as vital clues to the conclusion of this epic series***
