In a kingdom where magic is forbidden, Princess Elowen has spent her life hiding her growing powers. When the mysterious Lord Jasper Nightshade appears at court, she finds herself drawn to the charming nobleman with secrets of his own. But as their forbidden romance blossoms, Elowen discovers the truth: Jasper is the last heir of a family sworn to protect magic, now bent on destroying it—including the legendary Ember Rose, the source of Rosentia's power.

As the Phoenix Crown constellation aligns in the sky and her father's health fails, Elowen's magic grows stronger, harder to control. The connection between her and Jasper deepens, culminating in a passionate night that leaves her carrying his child. But Jasper's quest for vengeance threatens everything they've built. He must choose between his vow to destroy magic and his love for Elowen, whose very blood carries the power he seeks to eliminate.

With dark forces gathering at the kingdom's borders and ancient prophecies stirring to life, Elowen faces an impossible choice: protect the Ember Rose as generations of queens have done before her, or surrender it to the man she loves, knowing it will destroy everything—including her own magic.

As snow falls in summer and shadows lengthen across the land, Elowen must decide if love is worth the price of destiny.
