While orphaned Ogg, Rae, dreams of being able to socialise with humans, she doesn't expect to be welcomed into the home of two complete strangers. When she learns they're from another land and have no idea that humans are supposed to fear and hate Oggs, she begins to settle down and count them as family.

But when the mysterious phenomena that brought them there - great gashes in the sky that cause dramatic shifts within Culmina's landscape - suddenly get more frequent, the situation soon threatens Rae's new-found way of life. Discovering that the cause is the war between the Fae and the Dragon-people, who live on floating cities high above the clouds, she vows to put an end to it to save those she loves.

To do so, she must team up with the sassy ninth princess of the dragon-people, the down-trodden third prince of the Fae, and Max, a fellow orphan and hot-air balloon enthusiast. But when prejudice runs high and time is running out, can she get them to work together?
