I am sometimes suspicious of fantasy stories based on people from our world crossing into A Magical Land. This book is an excellent example of that trope working well.
Bridget is smart, tough, and competent, and it's a good thing, too, as she is plunged into a world where magic is rife and promises mean more than she is used to. She has to learn to navigate with the dubious assistance of the treasonous sorcerer.
There are three sequels, and each of them moves through a different part of Isavalta, replete with its own mythos and magical rules, characters and peoples and semi-people.
There is romance, but it's not easy or obvious. There is adventure, and heartbreak and heroism in ample measure. And at the end, I think Bridget is someone I would be proud to know.
