This Scottish girl jumps not to the past but another realm - book review of "The Source of Magic"

Delightful story with quite a few surprises. Jilian comes back to Scotland after her father's death. In the night she hears a voice calling her. A day later a stranger appears from thin air who hauls her into another realm. It seems her help is paramount to save that country.
The writer has a very pleasant style of writing and succeeds in building a world for us that comes to life on the pages.
