Tales of Elemental Spirits #1: Water Robin McKinley , Peter Dickinson

Seven tales describe magical beings that inhabit our waters. Some are familiar mer-people; some as strange as as a golden eye in a pool at the edge of the Great Desert Kalarsham, where the mad god Geljdreth rules; or the unknowable, immense Kraken, dark beyond the darkness of the deepest ocean, who will one day rise and rule the world.
