About This Book
Milo darts through the bustling streets of Highgate, heart pounding as the massive armada looms overhead. The Halcyon, a mysterious airship, slips past the blockade, its crew hunting him for a secret he barely understands. Just when Milo thinks he's safe, a shadowy figure blocks his path—what happens next could change everything.
Themes
Quick Assessment

The story includes themes of loyalty, bravery, and social challenges, but also contains child abuse, gun violence, and some obscene language and gestures, making it suitable for older middle-grade readers (ages 9-12) who can handle mature topics within an action-packed narrative.
