Amy Miller And the Ring of Time

Amy Miller just wanted something to remember her grandmother by. What she found in the attic was a locked wooden box, a faded journal, and a tarnished silver ring with a pulsing amethyst at its center. The ring felt warm. Alive. And her grandmother's handwriting in that journal said everything her family had never thought to ask: Amy, I know the ring will call to you. Take care of it, and it will take care of you.
Her parents dismissed it as costume jewelry. Her brother inherited the investments. Amy got the ring, and a legacy no one in her family could have imagined. The Ring of Time rewinds the clock by ten minutes. No more, no less. Enough to undo a mistake. Enough to change the outcome of a single moment. And in the wrong hands, enough to unravel everything. Amy is barely seventeen, still navigating the quiet grief of losing the one person who truly understood her, when the world she thought she knew begins to crack open.
Her grandmother wasn't just a warm and steady presence, she was a member of the Chronos Guard, a centuries-old secret society sworn to protect time itself from those who would weaponize it. And now that the ring has passed to Amy, she has inherited not just a gift but a target. The Obsidian Hand is coming for the ring. They are relentless, organized, and willing to do whatever it takes to seize control of temporal power.
With the help of the enigmatic Time Weaver, leader of the Chronos Guard, Amy is thrown into a world of clandestine operations, high-stakes chases, and decisions that carry consequences she can never fully predict, because every rewind has a cost, and time does not forgive careless hands. But Amy Miller is not the overlooked girl her family always assumed she was. She is resourceful. She is resilient.
And the more the Obsidian Hand underestimates her, the more dangerous she becomes. Amy Miller and the Ring of Time is a fast-paced YA sci-fi fantasy thriller built around a strong, intelligent female protagonist who must outthink her enemies, confront the ethical weight of power, and decide what kind of legacy she wants to leave, not just for herself, but for time itself. Perfect for fans of secret societies, time travel adventure, and heroines who fight back.
