It took me a while to warm up to Forbidden. I wasn't sure I liked a world with no emotions but fear and to be honest, I found myself quite bored at the beginning. 
 When the main character Rom starts feeling, though, I was blown away by the author's powerful descriptions. After that, it didn't take long for me to become so engrossed in the story that I could think about little else. 
 The characters, also, were nothing short of fantastic: all of them so different, so minutely shaped, I was at the mercy of their POVs and their first tastes of emotions. 
 Another thing I really liked and I'd been missing for a while before I read this, was the almost medieval setting, not as much as costumes and celebrations, but as superstition, government organization and the structure of the citadel. 
 I was quite shocked at the end, and terribly sad too, but I'll like to see how Mr Dekker will continue this adventure of his and if they will, indeed, find a cure for "insensibility". 
 I'm really looking forward to reading the next installment in the Book of Mortals series, and I may also look for Dekker's other works.
