Unfortunately, my introduction to the works of Kage Baker comes with the posthumous release of her latest novel “Bird of the River” ($25.99, Tor).The book follows the coming-of-age tale of a teenage girl named Eliss, who is caring for her addict mother and her half-breed younger brother Alder. Since the death of Eliss’ father, the family has moved from place to place, living with various “uncles,” some good, some downright nasty. In a last-ditch effort to save the family, Eliss manages to find a captain that will give her mother a second chance as a diver on the Bird of the River, a barge charged with keeping the river clear of snags and obstructions. But a diving accident leaves Eliss and Alder orphaned and having to find their own way aboard the ship.
