"Caer lived under a strange enchantment. Her father was King Ethal of the Shee-mound at Navan, a sorcerer so powerful that only the Dagda was his equal. Because of King Ethal's fear that Caer would one day marry a mortal man, he laid a curse upon her. This was her fate--to live every other year in the form of a swan on the cold, empty waters of Loch Bel Dracon".
Interesting, with pretty pictures, for independent readers. The illustrator does have trouble with faces, so that was distracting. No note about whether this is authentic folklore or original or how it represents Irish tradition, no bibliography or anything. No pronunciation guide. Back flap bios reveal only that the creators are scholars, not Irish themselves. I don't recommend it.
