Feathered - The Alex and Jackie Adventures, #2

Whenever Alexandra Caroline O'Rourke, AKA Alex, met with trouble, she generally blamed her younger sister, Jackie. And Alex's sudden engagement to marry a Viking prince, against her will, probably classified as trouble. If nothing else, a wedding held in 11th century Ireland would make it difficult to invite her friends from San Diego. Regardless of blame, Jackie was the only person who could help Alex, but Jackie was still in the 21st century.
And Jackie had her own problems, which included uncooperative fairies and strange songs which only she could hear. But most of all, if Jackie could not find a way to make it rain, marauding Vikings would be the least of their worries, because this is Feathered: being a fairy tale and this is an Alex and Jackie Adventure.
