I loved this book. I'm really into paranormal mysteries and this is one of the better ones I've read. 
One of the things I'm always looking for in fantasy books is characters who have knowledge about the magical world they live in. To me that makes the story more interesting. This book had that, two professionals who have worked for the organisation for over a decade. 
The Autistic representation was done well, the tiredness, the limit to the amount of background noice/people and the guilty internal voice. 
I thought the romance was also believable and cute.
