The Island of Morovia is shaped like a broken heart. The humans live on one side of the island, and the alkonosts - the bird-people - live on the other. But it wasn't always this way... Linnet wishes she could sing magic. But magic is forbidden and she has been banished with her father to the Mournful Swamp. She misses her old life, and dreams of reuniting with her friends. When her father is captured for taking a precious jewel, Linnet must set out on a treacherous journey. Travelling through alligator pools and sinking sands with new friends, she learns how to be brave, and discovers something even more powerful than singing magic. Something that could save her father, and heal the broken heart of her island once more... With themes of grief, trust, love, and that we have more in common than that which divides us, this is a heartfelt book filled with adventure and stunning storytelling from bestselling Sophie Anderson.
