Mia's Quest. Yucaipa's War, #3

A twin's bond. A hidden magic. A forest that chooses its own heroes. As the flames of war ignite across the kingdom, Mia Thorne's world shatters in a single night. Her brother, Kaiden, is wounded and missing. Shadow Elves have returned from myth to menace, and the noble Aguerius family-protectors of peace-are hunted from within and without. But Mia is no ordinary girl. Born with a rare connection to the ancient Trabar Magic, she can feel the river's current in her blood and the tremors of danger in her bones.
When a deadly ambush severs her from everything she knows, Mia must journey through the Sacred Forest alongside a mysterious elven guide, a sentient slime, and a magic only she can wield. To save her brother, to warn the other provinces, and to survive what's coming next, Mia must rise-before the forest's whispers become a war cry. Full of heart-pounding adventure, quiet wonder, and the deep power of family, Mia's Quest continues the sweeping saga of Yucaipa's War, where destiny, magic, and sacrifice collide.
