Broommates. The Alderwick Chronicles, #1

At Alderwick Academy, students learn to control magic. No one teaches them what to do when magic chooses someone else. Lucien Vale has enough trouble controlling his unpredictable magic without adding Cassian Thorne to the equation. Controlled, guarded, and heir to a powerful magical family, Cassian is everything Lucien isn't. They should have nothing in common. Then their magic begins reacting whenever they're near each other.
Forced together by a mysterious magical resonance, late-night study sessions become dangerous experiments, buried secrets begin surfacing, and the attraction between them becomes increasingly impossible to ignore. But something beneath Alderwick is waking. The halls are shifting. Ancient magic is stirring. And the impossible connection between Lucien and Cassian may be tied to something the academy-and Cassian's family-tried to bury.
Some bonds are discovered. Others are summoned. And some were never meant to exist at all. Broommates is an M/M magical-academy fantasy romance featuring opposites attract, forced proximity, slow-burn tension, forbidden magic, ancient secrets, a semi-sentient academy with boundary issues, and two witches discovering that the magic connecting them isn't the same thing as choosing each other.
