This fourth opus like a break after the 3rd which was so intense !! Finally, everything is relative, it happens quite a lot of things that will affect more ... full 5 is expected with great anticipation !! But here we encounter a little more secondary characters. Besides, I want to give a little advice as soon as you begin this saga, watch out for all those same characters who seem to have little importance !! At one time or another they resurface and have their action to be taken! Although this volume is very good, I have still a bit saturated, 4 in a row, it's a bit much! Nevertheless ...... strongly later !! because we would like to know what happens to our main hero !!
