If you are not familiar fantasy, as you say that this is the worst book to introduce you to the genre: fantastic creatures senchaînent one after the other without dexplications. One sometimes has the impression that Thomas Andrew wanted to put as much as possible in a minimum of creatures pages.
The same applies to Wave winks and allusions to the TV series and movies. There are so many quon end up wondering where lhommage begins and ends plagiarism.
The narrative is weighed down by inconsistencies, it juggles the investigation of the serial killer and Lanneau rather haphazardly without these intrigues quaucune really is hectic: better balanced between them and whether Drek kept talking about his deodorant brand preferred they could have been interesting.
So when 73%, Tony wakes up and announces that he Drek investigation into his death, this is the pompom on the Garonne.
To conclude: it could have been a fun supernatural denquêtes book if Drek wasnt dirty egotistical moron.
