Max and the Spice Thieves (Secrets of the Twilight Djinn)

Torn from all he knows on the worst day of his life, Max Daybreaker finds shelter as a cabin boy aboard a spice pirate ship led by the mysterious Captain Sin. Max is safe and getting used to his adventurous new life on the mystical three seas, when he learns his mom's disappearance that fateful day was a kidnapping. Now, nothing can stop him from finding her. An unlikely group supports his search-a teenage warrior princess, a three-eyed seer, a spy, Captain Sin, and his first mate, Piers. As their journey takes them through desert, ocean, jungle, and ice, they meet many magical creatures: shapeshifting bears, the Witch Queen, harpies, and the nightmarish Djinn, who command the dangerous Twilight Army. Max and his new friends soon discover that the Djinn will stop at nothing in their quest to enslave the world. Only a mythological stone called the Midnight Jewel holds the power to stop them, but will Max find it in time?
