Magisterium: The Iron Trial (The Magisterium), by Cassandra Clare
This is a slightly unusual series in some ways. It is a mix of new and old. The old part comes from the fact that it is a fantasy tale and talks about magic, mages, unusual creatures, etc. The new part is the fact that the story has an unwilling protagonist. A 12 year old boy who hates magic and is unwilling to go to the Magisterium.
Callum Hunt, the protagonist of our story has a sad past, his mother is dead and his left leg was shattered when he was baby. Another thing that makes him unusual is his hatred for magic, but it is quite understandable as his mother was killed in the Third Mage War. Despite all of this he has a relatively normal life, far away from the world of magic. His life starts to unravel on the day he is taken to the Iron Trial. The Iron Trial is a mandatory test that any child who shows signs of magic has to take. At the end of the test, each Master could choose up to 5 apprentices to teach.
