Dogsbody
Diana Wynne Jones
 The main action of this novel is framed as follows. Sirius, the Dog Star, has been falsely convicted of murdering a fellow "luminary" and of losing the Zoi, an extremely dangerous weapon that he has allowed to fall to a minor planet. He is sentenced to spend one lifetime in the form of dog, an animal native to this planet: if he can recover the Zoi within that dog's lifetime, he will be allowed to return to his former status as Sirius. If he does not, he will simply die at the end of his dog's life. Sirius accepts the sentence and is born into a litter of supposedly Labrador puppies. Revealed as mongrels, the puppies are thrown into the river in a sack. This is just the beginning of Sirius's problems. Although adopted by the loving Kathleen, he learns that she is "low dog" everywhere because she is Irish. Struggling with his limitations as a dog and his perceptions as a star, coping with the bigotry in the household, trying simply to get out on the street so he can begin his search for the Zoi, Sirius is battered by one setback after another. How he -- with help from Kathleen, another star, and his own quick wits -- uses his canine and stellar wisdom to track the lost weapon, is an intricate and intriguing tale. Many references are made to mythology, particularly Welsh mythology in the appearance and actions of the dogs (see Cŵn Annwn) and several later characters such as Arawn.
