Grace is strong (we'll know it), suffers the consequences of his gift (throughout the novel except the epilogue) and has caught the eye of Rio. Rio plays it a little caveman, but we used to, but I did not appreciate at all the side "you will not see your sister and do not argue I decide," I find it a bit limited, even if he can justify it rationally.
But it is not even that the most troublesome is really the aspect copy and paste the previous volume. The twists, the reasons, the characters changes, everything is deja vu. It is a pity that the author is not just broken ground on this one.
In addition, the paranormal side has fizzled and no longer plot.
I wonder how the author will manage to restore some life to everything, because then it stagnates and it's a shame, the beginning of the saga had rained pretty good.
