Eight participants, one goal: be the first to find the Heart before the court crumbles to ruin. Kamine is chosen as her village's participant for this year's Undertaking. Everyone knows her mother holds the record for beating the Undertaking, and finding the Heart in record time. Kamine has to prove herself as her mother's successor, and she only has four months to do it. The only problem? Kamine's powers have yet to manifest. Grimot, the new magic professor at Skola, Thunder Court's Undertaking Prep School, is a former Undertaking winner-although the methods he used to secure the Heart left him cursed by the Gods. Now, haunted by his past, he must ensure his students' success, before the hex takes hold. But when Grimot realizes Kamine is helpless, and standing in the way of his redemption, he offers her private lessons. Having no other choice, Kamine accepts, despite the obvious tension between them. With each passing lesson, the emotional barriers they've built begin to crumble as they reconcile with the tethers of their pasts, band together to protect the magic of the Thunder Court, and unearth the truth of Kamine's legacy. Of Thunder and Amethyst is the next installment in the Weather Court Gem series. Each standalone novella follows a different couple in their respective court (Snow, Thunder, Lightning, Rain, & Sun), each faced with the challenge of following their heart as the fate of their court's power rests in their hands.
