Introduction

The dragon touches down in a snow-blanketed valley, and for a single breath, there is silence.

Then the grief hits.

The survivors of the Palace of Souls carry more than wounds—they carry the weight of a kingdom that still belongs to a tyrant.

The story picks up immediately after a catastrophic battle, as Tory and Darcy Vega flee with their allies to a secret underground stronghold called The Burrows.

From there, the rebellion against Lionel Acrux takes shape amid ancient Phoenix training, shadow rifts, and the unbearable ticking clock of a fatal star bargain.

The novel spans months of preparation and ends in a siege that shatters the rebel forces, kills a central hero, and scatters the survivors under a sky rewritten by prophecy.

The cost, however, is Darius’s secret bargain—a marriage to Mildred and a deal with the stars that leaves him only one year to live.

He agrees to be her captive and plaything for three moon cycles in exchange for lifting the curse.
