An estranged uncle, a mysterious mansion, and Arthurian legend—together they lead to a world of magic and bloodthirsty wizards who want teenage Brinnie dead. Brynna "Brinnie" Lane has always lived a quiet life under the watchful eye of her hovering mother—until she's sent off for the summer to live with an uncle she didn't know she had. While her parents get to travel across the globe, she'll be spending three months in the middle of nowhere: upstate New York. It looks like she might spend the entire summer friendless with her nose in a book. However, she soon finds that Wraithwood Estate, her uncle's creepy old mansion, holds as many secrets as the man himself. When Brinnie is warned not to explore any of it, her curiosity only grows. As unnatural events take place and Brinnie hears whispers of a hidden war, she must unravel the truth about her family's mysterious past if she wants to survive. Something terrible happened at Wraithwood thirty years ago, and Brinnie is determined to find out what—even if it means confronting the possibility that magic is real.

The bane of Mordred, the son of Mordizan, and a millennia-old prophecy—together they may provide what Brinnie needs to defeat the world of magic’s greatest threat. More than a year has passed since Brinnie left Wraithwood, never expecting to see it again. But when Mordred captures her sister, she is thrust back into the world of magic. She flees to Wraithwood, where she learns of a prophecy located in the dark wizard capital of Mordizan that reveals the identity of “Mordred’s bane,” something that could destroy Mordred for good. Brinnie agrees to a rendezvous with Mordred to exchange herself for her sister, going undercover at Mordizan as a spy to find the prophecy and Mordred’s bane. There, she weaves a complicated web of secrets, lies, and tenuous friendships. She makes an unexpected ally in Marcus Vorath, son of the Master of Mordizan, who fears the implications of Mordred’s growing power. But in Mordizan, friends and foes may be one and the same. In the midst of court intrigue, battle, ominous new depths to her power, and searching for Mordred’s bane, Brinnie struggles to draw the lines. How far is she willing to go to destroy Mordred? And how much of herself is she willing to give up along the way?

The sword of legend, ancient magic, and a dead man's secrets—together they could save Brinnie's world or end it forever. Brinnie barely escaped Mordizan with her life. Battered and broken in body and soul, she knows she's running out of time. And though she has discovered the identity of Mordred's bane, no one knows where to find the legendary weapon. To discover the truth, she and Marcus must journey to Castelon and seek the aid of the Council. However, their actions at Mordizan brand them as enemies and war criminals. Between Mordred's armies engaged in full-scale war and the political machinations of the Council, Brinnie struggles to balance the battlefield and the courtroom while estates fall before Mordred's wrath. As magic ravages her own body, threatening her survival, the allure of ancient, forbidden power grows brighter. And only one man holds the knowledge of the weapon that could destroy Mordred once and for all—a man they buried in the gardens of Wraithwood.
