When Rose begins the new school year alongside her best friend, Lily , she has no idea how quickly their world will spiral out of control. Enter Corvin Malric —mysterious, magnetic, and dangerously perfect. The handsome teenage son of Seabrook High's new science teacher seems like a dream come true—and to Rose, he is. But not everyone is so easily charmed. Lily senses something dark beneath his flawless exterior, and Jasper Sylvan , Rose's loyal science partner, feels it too. Then tragedy strikes. A beloved local shopkeeper is found dead under suspicious circumstances, and the shadows over Seabrook deepen. Rose and Lily soon realize this is no ordinary death—someone is after the Crystal Box and the gemstones hidden across time. Clues from an old Seabrook painting and cryptic entries in Brigid's diaries lead them deeper into a tangled mystery surrounding the second stone. But as Corvin slowly isolates Rose from the people who love her, his grip tightens like a vice. One by one, her friendships begin to crumble, and her once-unbreakable bond with Jade fractures into a heavy, heartbreaking war. All the while, a raven follows her every move—silent, watchful, ever-present. Yet the most devastating blow comes from the boy she believed to be her soulmate… when he reveals a far more sinister agenda than she ever could have imagined. And when Rose discovers that it's not just the amethyst protecting her—but also the fierce love of her mother and the unbreakable loyalty of her friends—she realizes the true strength she's carried all along. It's a lesson she must learn the hard way. But when she's forced to fight for her life, Rose awakens the ancient magic running through her veins… and the fire that's been burning in her soul all along. But despite her friends' best efforts to protect her, Rose mysteriously disappears. It is up to Lily , Jasper , and Carter to unravel the trail of clues before it's too late. Before she becomes the next sacrifice in a centuries-old battle for power. AMETHYST is the spellbinding second installment of The Crystal Box Series—a thrilling YA fantasy of magical power, ancient legacies, heart-pounding danger, and the unstoppable strength of a girl awakening to her destiny.
