I'll start this review with one phrase "Time travel is a nightmare to a writer unless he/she has good space-time mentality".
With that said, lets start with this review of a sort of confusing and frustrating series. First of all I do read all the series one book after the other in a lapse of 4 days so the confusion is not on my side since I have all the story fresh in my mind.
The story follows Heaven and Colton in the nightmare and Sci-Fi story their life turned into. They didn't knew of each other in the beginning but their lives were entwined in a way neither of them could foresee. Both follow different paths that guide them to meet around the middle of the first book and they solve their first conflict to protect the ones dear to them (more to Heaven than to Colton but anyway). Not wanting to be a spoiler I'll close the review of the first book with that and say it is a really good premise for a new world, it even have a reasonable (although a bit mystic) way to explain their powers. A world where every person with power has a counterpart; the sources that produce energy have a conduit counterpart that can channel and enhance that energy.
Now to the second book; and here is where the thing turns kinda frustrating and confusing. The excellent story built by the author in the first book goes on, new dangers and old enemies come back to destroy everything, again. The point where this good story goes awry is when Colton makes decisions based on what Elena told him... the slight issue with this... Colton never met Elena more than a few minutes and she was unconscious when they first met and when she recovered enough to talk he was unconscious somewhere else. Being optimists and forgiving the Author for the slight slip of continuity we will blame on the time traveler blaming him of creating a paradox and think we slipped to another reality where Colton and Elena do talked... theory that is crushed in the third book where said time traveler explains the paradoxes created when he saves Heaven once and again and says that there was no paradox going on the moment Elena could have met Colton.
My Verdinc... 3 stars, The bases of this new universe are really interesting, if it wasn't for the frustrating part where something that never happened affects the story then everything would have been excellent and 5 stars would be marked in the series; I'll try to contact the author an point this, lets see if there is some kind of explanation for this.
