Eleven-year-old Darwen Arkwright has had a lot of changes in his life recently. Three weeks ago, he was living with his family in a small town in northwest England, and now he is living with his aunt Honoria in Atlanta, Georgia. There, he has to adjust to a new home and a new school, where his accent makes him stick out like a sore thumb. Things get even more complicated when he meets old Mr. Peregrine, a shopkeeper who gives Darwen a gift--a magical mirror that is actually a portal to another world. When Darwen travels through the mirror to the world of Silbrica, he discovers a beautiful land filled with magical creatures. But some of those creatures are actually quite dangerous and are trying to open up the gaps between the worlds. With the help of new friends Rich and Alexandra, Darwen vows to stop these creatures from getting through the portals because if they do, no one in this world will be safe.
