Call shouldn´t worry of returning to the Magisterium because everyone knows: the Enemy Of Death is dead. But there is a spy in the Magisterium who seems to know that, in fact, the Enemy´s not truly dead but his soul lives inside of Callum. So Call, Tamara and Aaron have to find out who the spy is before they reveal his true identity to the whole magic world.
There isn´t much to say about this book since it´s the third in a series just that I´m still a big fan of this series and that I´m the biggest Sherlock of all time because I knew who the spy was since reading a super small but very important detail in the second book. And no, it was not that obvious so the spy´s identity is still gonna be a surprise to you. It just wasn´t to me because of two words written down in the Copper Gauntlet and I am, in fact, pretty proud of myself so I´m gonna say it again: I´m the biggest Sherlock the world has ever seen.
