To be honest, I was a bit disappointed with this book - with the last two books of the series to be more precise. 
 The book started in a very slow pace describing everybody mourning Jim and finally trying to save him from the desert, i.e. the nothingness. Later in the last a hundred something pages, Jim is trying to squeeze the saving of two lost souls. Obviously everything was rushed and the ending was really sudden and completely predictable. 
 Devina was again the most interesting character. I was thinking if this book was a movie, she would probably be the only Oscar winner of the film. Brilliant performance crying over Jim's body, fighting her OCD and being crashed under her lover's betrayal
