Shooting star (trollhunters)

Cyrene Lunaris-Solmire used to think the strangest part of her life was the antique, star-shaped hairclip she'd kept since childhood. That changes the night she wakes up drenched in cold sweat from a dream that feels less like a fantasy and more like a stolen memory, a fragment of a life, a world, and a power that isn't hers.

She isn't alone. Her closest friends-Cerydra, March 7th, Hysilens, and Cipher-are waking up with the exact same cosmic déjà vu, their minds plagued by beautiful, fragmented visions of an ancient, starry past. But there's no time to decipher these celestial puzzles when Arcadia Oaks reveals its own massive secret.

When their classmate Jim Lake Jr. uncovers a magical amulet and becomes the legendary human Trollhunter, the hidden world of Trollmarket comes crashing into Cyrene's reality. In that exact moment of danger, Cyrene's childhood hairpin ignites with a dazzling, radiant starlight, awakening a legendary power within her to shield the people she loves. Now, Cyrene and her squad are pulled into a secret underground war, fighting side-by-side with Jim to protect the good trolls from dark, monstrous forces.

But as the battles beneath Arcadia grow fiercer, the surface world gets weirder. The dreams are multiplying, turning into vivid waking visions, and the lines between their ordinary teenage lives, the subterranean troll lore, and the vast secrets of the cosmos begin to blur. Cyrene is about to learn that her magical transformation is just the first step in a much bigger destiny because when the stars call, the universe listens.
