During day, Stiles belongs to a pack back in Beacon Hills, fighting the supernatural. During night, he takes on his identity as Mischief, being part of the Justice League's secret operation team. For two years he's lead this double life, unboknowst to his friends. Will an upcoming alien invasion from the Reach change this? Will the pack discover Stiles' secret?

The pack has lost hope on finding Stiles again, gone missing more than two years ago. However, in a trip to San Francisco to the world's most famous circus, things change when they find their friend where they at least expected to. It takes them a while to realize something's not right and that the circus might be hiding more than a few performers capable of doing the impossible.

This is a sequel to The Swords' Master. After the attack, Stiles thought the prophecy was fulfilled. However, he soon discovers there is much more to being part of a prophecy. The brotherhood is threatened again, but by what they had least expected. Together with the pack, Stiles will have to figure out why werewolves are after him and also figure out his new magical abilities.

Stiles feels like there is no place for him in the pack. He feels useless and alone. Until one night his jeep brakes down, leaving him next to the woods. After seeing something rare in there, he decides to go in and investigate. He wouldn't have imagined what would occur and what events would follow. He starts to discover his new identity and to realise how powerful he truly is.
