There's not a single person in this world that doesn't have a price or a threshold where they'd give up their morality for something that benefits them or someone they care for." Kilian Sterling is a medical researcher who's discovered a possible cure for cancer, all while battling a chronic illness that has slowly taken over her life. As clinical trials begin, Kilian finds herself desperate not only for a cure for herself, but also for her best friend, Aiden, after he volunteers in her clinical trial. Desperate for relief from her illness and willing to try anything, she meets Stolas-a mysterious, beautiful, otherworldly figure who she believes to be her spirit guide. As she grows closer to him, she begins to question what he truly is, where he comes from, and what he wants from her. As the trials spiral out of control and Kilian's health deteriorates rapidly, danger closes in from all sides. The more she uncovers about the trials and Stolas, the more she realizes the stakes are far higher than she could have imagined. Her body and mind are in a race against time as the truth about the trials-and the forces surrounding her-begin to unravel in terrifying ways. Will Kilian survive long enough to finish the trials, or has she already run out of time? Find out in Convalesced, book three of the Prince of Hell series.
