"Concrete Crown" by Amanda Savage tells the story of Cassidy Thorne, a self-made woman from Austin, Texas, whose life is upended by vivid dreams of castles and ancient figures. These dreams awaken dormant magical powers within her, leading to the arrival of Alistair Beaumont, who reveals her inheritance: a vast global business empire and a lineage connected to King Arthur and Morgana le Fay. Cassidy learns she is the heir to a powerful magical legacy and faces immediate threats from shadowy figures seeking to control her power. Alistair becomes her guardian, guiding her through this bewildering new reality, revealing ancient bloodlines, magical abilities, and hidden dangers. Their initial outing to a farmers market results in a public display of Cassidy's power, attracting unwanted attention and confirming the reality of her heritage. As Cassidy delves deeper into her family history with Alistair, she discovers ancient documents and cryptic symbols that speak of generations of power, secrecy, and betrayal, intertwined with Arthurian legend. She learns about the Thorne ancestors' involvement in shaping history and the magical battles they fought. A near-fatal car accident confirms the danger she is in, and the narrative follows Cassidy's awakening powers and her entry into a world far beyond her previous comprehension. The story continues with Cassidy's introduction to the corporate world of Thorne Industries in London, where she faces skepticism and potential enemies among the executives. She also discovers a hidden library containing ancient artifacts and journals that reveal the magical history of her family and a secret society, the Order of the Silver Crescent, dedicated to protecting her lineage. The journals also speak of the Obsidian Hand, a shadowy organization seeking to exploit the Thorne family's power. Cassidy undergoes intense training to hone her burgeoning magical abilities, guided by Alistair, who is revealed to be more than just a guardian, with his own secrets and a deeper connection to her family history. A trip back to her childhood home in Texas triggers fragmented memories and hints at a connection between her past and her current struggles. The narrative builds towards a confrontation at the Coronation Ball, a seemingly social event that is revealed to be a potential battleground. Unexpected guests arrive, including representatives from the Seelie Court and the Shadowfell, as well as Cassidy's estranged aunt, Morwenna, presumed dead. The ball becomes a chaotic clash of magic and wills, revealing betrayals and solidifying alliances. Alistair's true identity as an ancient Guardian of Avalon is unveiled, marking a significant shift in the power dynamics. Following the tumultuous Coronation Ball, Cassidy and Alistair navigate the complexities of Avalon, facing threats from within and without. They uncover the truth behind Isolde Thorne's disappearance and the existence of Rhys, Cassidy's half-Unseelie cousin. Cassidy embraces her full power, choosing to heal the rift between the mortal and Fae realms, a decision that comes with personal sacrifice. The story progresses through Cassidy's trials of power, her exploration of Avalon, and her learning of the ancient magic of her lineage, connected to Morgana le Fay. She faces a pivotal choice regarding the extent of her power and ultimately chooses to embrace her full destiny.
