Wexler is an able builder of magical worlds and creatures, with labyrinths, an enchanted library, and a feisty, swashbuckling heroine at the centre. A story rich in action and allegory.

Heartbreaking sacrifices, joyous reunions, and poignant partings round out this rousing old-school fantasy adventure

The Iron Trial is merely a setup and introduction, and promises to take subsequent instalments of the Magisterium series in a more complex and philosophical direction

This is an incredible book . . . once you've started reading, its hard to put the book down. It's awesome! It's full of suspense and I cannot wait for the next book in the series to be released!

The strange, subterranean Magisterium is vividly rendered, and a string of ominous revelations will leave readers eager for future installments. Fans of both authors will enjoy getting to know this well-rounded cast in the first steps of their adventure

The third-person narration, filtered through Callum’s delightfully insecure-and- overcompensating-with-snarky-bravado perspective, carries a tone that will likely have readers chortling in recognition. A promising beginning to a complex exploration of good and evil, as well as friendship’s loyalty

I definitely don't want to give anything away about the ending, but I have to give the authors credit for a really stunning climax which had me desperate to get my hands on the next in this 5-book series. I can't wait to find out where we go from here!
