Moonchild: Voyage of the Lost and Found: Book 1 (The Moonchild series)

A magical new middle grade adventure from a rising star author, inspired by The Arabian Nights
The Sahar Peninsula lies just beyond the horizon, but it isn't the easiest place to get to. No maps will take you there, nor can it be charted by gazing up at the stars, or down at a compass...
Twelve year old Amira has only ever known a life at sea with her sea-witch mothers. So when their ship is wrecked in a great storm, Amira is delighted to have an opportunity to explore land – accompanied by her best friend Namur – a jinn in cat form. Amira soon finds a boy who has a jinn like her, and learns that their spirit companions are connected to the mysterious storm that gets stronger each day.
When Namur goes missing Amira discovers she has to visit a magical place; a place where lost things can be found. But will Amira also discover her own destiny, and find out what it truly means to be a Moonchild?
