When Yann the centaur is stabbed through the heart by a unicorn horn, the life-threatening injury needs a magical remedy. Helen and her fabled-beast friends unite, with the help of the dragons, to find a magical token with the power to heal him. But they only have until tomorrow night. The friends split into teams: Lee, Helen and Sapphire search for King Arthur’s scabbard; Catesby, Lavender and Sylvie search for hidden gems in a cliff face; Rona and Tangaroa wash a flower in seven waterfalls at sunrise. But will they complete their missions in time to save Yann? And with their arch-enemy, the power-crazed Master of the Maze, on the loose once more, danger is never far away. This is the fourth and final book in Lari Don's popular First Aid for Fairies series.
