Vivienne Valeran has vanished.

The tear that took her left no body, no trace and no way back. Only Diego can still feel her, a faint spark through a bond that should have broken.

While Vivi fights to survive the Grey Between, Estralia begins to fall. Wards fail. Islands crack. Magic drains towards the place where she disappeared.

Then Gwyn finds the truth. The tear was crafted and the spell bears Ravenna's mark. To bring Vivi home, Diego will have to open a path no one should touch. But something ancient is waiting on the other side, and it doesn't only want Vivi.

It wants out.
