The war for Valyros has begun. The bell that never tolled now looms above a city tearing itself apart. Armies gather at the gates. Betrayal festers in the council. Symbols of the Old Warden resurface on banners, twisted into the mark of treachery. And at the center of it all stand two men whose bond should never have survived, yet refuses to die.

Prince Ithriel has walked from vengeance to crown, from heir to outcast. The council calls him traitor. The people whisper of his hesitation. The throne demands he spill the blood of his enemies—including the one man he cannot let go. To lead Valyros means to sacrifice Kaelis. To save Kaelis means to abandon everything Ithriel has sworn to protect.

Kaelis no longer hides in shadow. The assassin has become the Blood General, inheritor of Lord Varandel's legacy. His father's betrayal burns in every scar, in every command carved into his marrow. To the armies of Valyros, he is weapon and warlord. To Ithriel, he is chain and temptation. To himself, he is a question: son or traitor, blade or man, shadow or salvation.

Their bond—cursed, bloodbound, relentless—beats against every command, every crown, every betrayal. It is stronger than chains, sharper than oaths, more dangerous than war. On battlefields drenched in fire and ash, Ithriel and Kaelis fight side by side, only to find themselves face-to-face with the truth: their love is the city's undoing, and its only hope.

Varandel does not rest. His treachery coils tighter, his mark spreads farther, his ambition swallows armies. Father against son, prince against crown, council against people—the final war consumes them all. In the silent shadow of the bell tower, Valyros will either shatter or be reborn.

But amidst ruin, two hearts cling stubbornly to one another. Ithriel cannot sever the bond without breaking himself. Kaelis cannot raise his blade without betraying the one soul who sees him as more than a weapon. Their enemies call them doomed. Their allies call them cursed. Yet together, they burn brighter than any crown, fiercer than any army.

Bloodbound Hearts concludes the saga of Thorns of Destiny, where:

This is not a gentle romance. It is a story of war and sacrifice, of crowns forged in blood and vows reforged in love. It is the tale of an assassin and a prince, a traitor's son and a city's heir, two enemies who defied every command and discovered that love itself can be the sharpest weapon of all.
