Alien World. Completely alien... and yet so familiar. The world of Flying and Floating Islands, the world of steam airships and pointy-eared non-humans. It is dominated by iron, steam and coal, curiosity, passion and... The third, Alien Force. It carries airships upward, splashes out like fiery jelly from the suspended cocoons of shock ornithopters, makes the limbs of assault arachnids and combat exoskeletons move, seeps into the brains of tactical tablet operators and control systems... This is magic. A midshipman of the Imperial Aeronautical Corps, the heiress of an aristocratic dynasty, a taciturn, slightly ironic master, an expert on the Third Force - the heroes of this story will have to go through many tests, become closely acquainted with the cruel Inri race and other aborigines of this world, who are not always friendly in relation to people. And also - to meet guests from another world, where their own ancestors once came from...Are they ready for this?
