Books with title Magician's Wife

Tobin Wells and his classmates continue their studies in the magical kingdom of Elden Forest, with a summer project installing the new Travelling Mirror Network. But when one of the mirrors malfunctions, Tobin and his friends are thrown headlong into a peculiar maze of mirrors, traversing strange new lands, and encountering fantastic new magic, including Shrinking Spells, Fast-Food Bottled Brews, and an unfortunate encounter with a river that turns unwary travellers into fish! With their resources running low, time running out, and no obvious exit from the increasingly dangerous maze, Tobin must find a way to get himself and his friends back home to Elden Forest before it’s too late!
