The final instalment in this dragon-filled, emotional, spicy romantasy trilogy for lovers of Fourth Wing and Jennifer L. Armentrout. Rhea was almost free. Snatched from Prince Torrin’s castle, she’s now a captive of Tarakona’s enemy – the Fenuaheran military. She's not just a prisoner, she's a weapon to hone. The military, uniquely, has the means to train Captain Alaric Fuller, another First Bloodline Anamali. Tall, golden-haired, and smug, he can teach her how to defeat the magic-stealing Youngbloods. Thorne is torn between his loyalty to Rhea and his newfound family, who just so happens to be her captor. Without his magic, he is rediscovering who he is – until the coughing starts. The sickness that should take him in twenty years has arrived early. With war upon them, Rhea has to face new facets of her power, including the dark magic that lies within her. But the more powerful she is, the more effective she is as a weapon. Can she gain enough control to save Thorne and return magic to Tarakona before Fenuaheray destroys her?
