The Balloon Thief

For Khadija, the only escape from her arranged betrothal is the sky. When she spots a rogue hot air balloon fighting against its ropes, she leaps at the chance for adventure. She soon finds an unlikely ally in a poor glassmaker's apprentice, Jacob. But Jacob is a Hari, and Khadija a Ghadaean. The Hari are oppressed and restless and the ruling Ghadaeans brutal in their repression. The Hareef use forbidden magic, summoning jinn - wicked spirits made of fire - to enact their revenge, forcing Jacob and Khadija to choose what kind of a world they want to save.

After the battle of Al-Shaam - where the invading jinn army was defeated - Khadija, Jacob and their friends are heroes. Then, Khadija receives a letter: her sister, Talia, has been kidnapped and stolen into the magical realm of Al-Ghaib. Accompanied by Darian - who has been different since jinniya Queen Bidhukh's parting blow - Khadija embarks on a quest to rescue Talia. But Al-Ghaib, where the sky is emerald green, is a place of trickery: Khadija will have to have all her wits about her if she's to outfox her sister's captor.
