"Once a Witch" by Carolyn MacCullough follows Tamsin Greene, the seemingly talentless daughter in a family of powerful witches. Struggling with her sense of belonging, Tamsin’s world changes when a stranger mistakes her for her talented sister, leading her into a quest that uncovers dangerous family secrets and a centuries-old feud. As Tamsin races to protect her loved ones, she must unravel the mystery behind her own seemingly ordinary existence and the prophecy that surrounds her. Through encounters with magic, betrayal, and newfound romance, Tamsin discovers her true power and the importance of embracing her identity to shape her own destiny.
Tamsin Greene has always felt like an outsider within her own family. Born into a prominent witch clan in upstate New York, she alone appears to lack any magical ability. This perceived inadequacy fosters feelings of resentment and alienation, driving Tamsin to seek solace in her mundane boarding school life and distance herself from magical matters at home. But her world is upended when a mysterious stranger enters her family’s bookstore with a request, inadvertently involving her in a larger magical conflict and awakening questions about her identity.
The Greene family, revered among witches, hides wounds and secrets beneath a veneer of unity. Tamsin’s relationship with her sister Rowena, celebrated for her magical talent, is both supportive and fraught, reflecting the pressures of expectation. As Tamsin delves deeper into the family history and investigates the stranger’s request, she uncovers a dark past and a prophecy tied to her own fate. These revelations cast her family’s legacy in a new, troubling light, forcing Tamsin to reckon with betrayal from both within and outside her clan.
The thread of destiny versus free will weaves throughout Tamsin’s journey. Initially resigned to a mundane life, she must decide whether to accept the role foreseen for her or forge her own path. The choices she makes—guided by instinct, intellect, and emotion—have significant consequences for herself, her loved ones, and even her entire magical lineage. The story explores how even a perceived absence of power does not preclude agency, and how true strength emerges in critical moments of self-determination.
Magic is central to the narrative, not just as a tool but as a crucible for moral and personal dilemmas. Tamsin confronts the seductive potential of power—how it can lure even the well-intentioned toward destructive choices. She witnesses firsthand the corruption of magic through those who pursue it selfishly or use it as a weapon. Ultimately, Tamsin learns that responsibility, wisdom, and restraint are just as vital as raw ability, deepening her understanding of what it means to wield power.
Interwoven with the magical intrigue are themes of romance, loyalty, and betrayal. Tamsin’s evolving relationship with childhood friend Gabriel adds warmth and complexity, providing support as she faces mounting adversity. Meanwhile, fractured loyalties and shocking betrayals test her resolve and force Tamsin to confront what she truly values. In embracing her heritage, she not only uncovers her unique power but also redefines her role in her family and the fate of all witches.
