The Rainshadow Orphans: The Rainshadow Series, Book One,

The first novel in a dazzling epic fantasy trilogy inspired by Japanese folklore and Studio Ghibli, set within a mythical archipelago brimming with dragons and Sun Spirits, high-tech hackers and bubble tea. Life is hard for the inhabitants of Rainshadow City, a place where poverty and corruption are rife and where they are terrorised by an underground criminal organisation known as the Lucky Crows. Toshiko, Jun and Mei Kawakami are a family, bonded through loyalty if not blood, who live outside the law and who are seeking revenge for the murder of their beloved 'aunt' Reiko. Haru is the son of the Emperor, destined to one day rule over the Archipelago and uphold his mother's ignoble legacy, but he is more interested in making friends with the magical Sun Spirits it seems only he can see. Theo, forced to leave his homeland, is a reluctant foot-soldier for the Lucky Crows. He doesn't want to be a gangster, but as an illegal immigrant to the city, his choices are severely limited. When Toshiko steals a dragon pearl from the leader of the Crows, it sets them all on a thrilling path which will determine the future of Rainshadow City. Set across two days and peopled with unforgettable characters, The Rainshadow Orphans blends fantasy and science fiction to explore what it means to stand up to corruption and take charge of destiny.
