Shadows of Change by Zora Stone

Living with sentient shadows isn’t exactly a recipe for staying under the radar. Just ask Kaia Draven, who’s spent twenty-three years pretending her shadows don’t have opinions about everything—including her disastrous love life. But when a Nightwraith attack forces her shadows to show off their teeth, Kaia finds herself recruited to Arcanum Academy, where magic isn’t just studied—it’s a deadly serious game.

The academy might be beautiful, but its politics are vicious. As a member of the scorned Faction of Shadow, Kaia should be keeping her head down. Instead, she keeps collecting complicated allies: the impossibly gorgeous twins with fire and water in their veins, a chaos mage whose humor masks surprising depth, and a dangerously charming prince whose darkness calls to her own. Her shadows, naturally, have opinions about all of them.
But attraction becomes the least of her problems when ancient magic begins stirring within her, awakening powers she never knew she possessed. As her abilities grow stronger and her bonds deeper, dark forces gather. Someone wants to claim both her power and her heart—and they’ll tear through anyone who stands in their way.

Welcome to Arcanum Academy, where magic has consequences, shadows have attitude, and falling for multiple powerful mages might be the least of Kaia’s problems. Probably.
