Sci fi, werewolves, daemons, witch actions, erotic dreams, time travels, shapeshifters, drug addiction...
There is a lot to pick up, and there are different narratives throughout the book. I was lost, the fact that the heroes themselves were slowly discovering their capabilities, their powers and their story didn't help . At one point, I felt like I missed the whole plot.
This book seems like the prequel to a very good serie and the action looks interesting : to fight a powerful vilain (a demoniac shapeshifter) who wants to destroy the world.
