By Deary, Terry 

Retelling of the tale of Prometheus, in which Prometheus becomes a time traveller in order to escape the wrath of the gods and befriends a Victorian orphan. Prometheus gave fire to humans and was punished for it--only in this story, Zeus frees him and gives him a quest: find a human hero and Theus will be forgiven. The story of Theus alternates with the story of Jim, an orphan and a thief in 1858 who is narrating the whole book, in very funny style. In each volume of the trilogy, Theus befriends different characters as he travels through time.

By Farmer, Nancy  After escaping from the Sea of Trolls, the apprentice bard Jack plunges into a new series of adventures, traveling underground to Elfland and uncovering the truth about his little sister Lucy.The children from the sea of trolls brave their worst nightmares -- underground. Jack is amazed to have caused an earthquake. He is thirteen, after all, and only a bard-in-training. But his sister, Lucy, has been stolen by the lady of the lake; stolen a second time in her young life, as he learns to his Terror. Caught between belief in the old gods and Christianity (790 ad, Britain), Jack calls upon his ash wood staff to subdue a passel of unruly Monks, and, for his daring, ends up in a knucker hole. It is unforgettable -- for the boy and for readers -- as are the magical reappearance of the Berserker Thorgil from a burial by moss; new characters Pega, a slave girl from Jack's village, and the eager-to-marry-her bugaboo (a hobgoblin king); Kelpies; Yarthkins; and elves (not the enchanted sprites one would expect but the fallen angels of legend). Sequel to Sea of Trolls.

By Farmer, Nancy  After Jack becomes apprenticed to a Druid bard, he and his little sister Lucy are captured by Viking Berserkers and taken to the home of King Ivar the Boneless and his half-troll queen, leading Jack to undertake a vital quest to Jotunheim, home of the trolls.
