I originally read the first in this series in middle or high school and enjoyed it, but I was never able to find any other book in the series. Finally, I decided to make the move and ordered the next two "Quantum Prophecy" books (only just finding that the series was renamed?) and see if I could finish the series.
Plot Overview: Picking up where the last novel left off, the new heroes Colin (son of former superheroes Titan and Energy) and Renata (known as Diamond) have returned to Colin's home in Ireland and are fighting crime and saving lives as costumed vigilantes. Meanwhile, Danny, who lost his powers and his hand in the last book's finale, is trying to adjust to life without the man he believed to be his father, now revealed to have been the former shapeshifting supervillain Façade. When someone reveals their identities to the world, the kids and their families move to Sakkara, the new hero base organized by the U.S. government and based in Kansas. Sakkara is run by Josh Dalton, the brother of the last book's villain Max, as well as Paragon, also known as Solomon Cord, who has a supersuit similar to Iron Man. There, they meet a few other superpowered kids who are also training.
Meanwhile, Dioxin, a former supervillain who was assumed dead, begins working with the Trutopian community, an organization that proposes to end all crime by creating secure communities with strict rules, almost like a cult. This organization has evil plans, of course, and a mole in Sakkara which spells trouble for the new heroes.
Review: Honestly, still a pretty solid follow-up to the previous book. Other reviewers point out the irresponsibility of the adults in this book, since they are letting the 13- and 14-year old heroes deal with deadly situations, and yes, of course, that happens. It's a middle-grade book, and the characters that age have to be the heroes and main characters. But to be honest, and fair, there are plenty of superheroes in Marvel and DC who are the same ages and do the same thing. So, to me, it wasn't a big deal.
Overall, I think the balance worked out pretty well between the adults and kids. Since the kids are the ones with superpowers, it makes sense that they are a bit more engaged. however, for the most part, they spend their time training, which is logical. The adults don't really act stupidly or illogically in order to make the kids shine more, which is appreciated. I honestly would like to see more of them, but understand why that's not happening. The kids are the superheroes, and the heroes of the book... we don't need Titan's midlife crisis about not having his powers. The parents and adults are still able to act heroically without powers and put their lives on the line just as much, and I respect that.
My main gripe, really, is that this plot, like the first, deals with the group being manipulated by a mole in their operation, and it's pretty clear who it is the whole time (and probably, the person's real identity.) As a kid, would I have noticed? Maybe not. But since this is so similar to the first book, you already know to look for the signs. It was a bit of a let down, but it didn't ruin the book.
I still look forward to FINALLY finishing the series after all these years, and I still respect the book for being able to stand on its own in a genre so flooded with heroes from only two companies. The superhero and superpowered genre has a lot of potential (just as much as magic or mythology, since that's essentially what it is) and it's a shame that everyone is overshadowed so much by Marvel and Dc.
