Shapeshifter continues the engaging adventures of Niall Flynn, Irish professor, and his American-born daughter, Caitlin, and their friends, the strange people Below-Ground who subsist on a mysterious and magical red fluid and can't stand sunlight. As Caitlin ponders her future - college in Ireland or the US, and just how does she feel about her Below-Ground friend, Fortescue - things get even more interesting. Her cat turns out to be a silver-haired smart-aleck fairy in disguise and he and his people need help. Someone is kidnapping the Fair Folk, the Tuatha de Danaan. Why? Who? Can they be found and rescued before it is too late? Add in the complications of love in its many permutations, and Bastine is once again taking her readers on a wild ride of magic, mystery, love and friendship on the Emerald Isle. - from Amzon
