A classic tale of Partholon

Shannon Parker, doing a little shopping while on summer vacation, hears an antique vase call to her and suddenly finds herself transported to Partholon where she is hailed as the Goddess Incarnate of Epona, and she must find a way to get back to Oklahoma before her newfound enemies kill her, or she is forced to marry a centaur.

Shannon Parker, preoccupied with her pregnancy, nearly forgets her life on Earth until a power surge sends her back to Oklahoma without the magic she needs to return to her centaur husband on Partholon, but the help she finds is a man as tempting to Shannon as her own husband.
