Thanks to a wise advice I was given, I avoided nightmares by not reading this at night, but I'm afraid ghosts were just another matter altogether... I feel like this series has finally reached that level of creepiness I've always heard talking about but couldn't completely get. Indeed, "Dead Sky Morning" was the right instalment to make me freak out with lots of "What?", "No way!" and "Eww!" (perhaps sometimes 'accidentally' escaped as "Aww!") freely flying around during the whole read.
With mysterious appearances and quite the spooky setting, the story was as much intense as Perry and Dex's issues were. Boy if the tension between these two grew higher and higher in every chapter, and boy if it was as exciting as all the discoveries (big revelations!) made through this special journey. Let me tell you, with the new information gathered and with things ending the way they ended (did they?), I'm more than eager to read the next book because, guys, it just got very interesting!
