Cyrus Beldon was born to kill vampires. Or so says his indomitable family legacy.

For generations, the Beldon hunters have kept the peace between humans and vampires, navigating tense diplomacy with the elite Honorable Families and eliminating threats when needed. Cyrus is content to leave the hunting and slaying to his capable older siblings, but when his oldest brother is murdered by Honorable vampires in a shocking break of the truce, Cyrus becomes determined to find out why his brother was not merely killed, but turned into a bloodthirsty creature known as a Wild vampire.

Cyrus's hunt for information on the monster that became of his brother leads him to discover an experiment suggesting that recently-turned vampires can have their humanity restored, and with this revolutionary possibility within his reach, Cyrus dares to hope for a future in which he can save vampires instead of killing them. He traces the studies back to one of the five Honorable Families, and with the help of studious and infuriatingly proud Lucien Vista, Cyrus delves into vampire biology to seek the core cause of Wild turns-and a cure for them.

Amid multiple high-profile murders, rising tension between the Beldons and the Honorable Families, and dangerous sparks between Cyrus and Lucien, the truce is at a tipping point, and Cyrus and Lucien must decide how far they are willing to go to keep the peace between their families-or if it's already too late.
