This is yet another in a long line of sorry-ass first person voice novels. I loathe that voice. Once in a while I've found an author who can carry it, but for the most part it's far too limited, self-serving and self-obsessed, and it turns me right off. I'm at the point now where I'm not even going to read a book, no matter how interesting the blurb makes it sound, if it's in worst person. There are lots of other books out there that are far less annoying!
The story is about this 14-yer-old boy who has the super power to change his bone density. How that works without his changing his muscles to cope with the weight, is left completely unexplained. So we have yet another example of a writer simply not thinking his story through so we have magical powers here! Worse though, is that this super hero story is far too derivative of every other super hero story, particularly of the DC comics canon, of the 2005 movie Sky High, and of the lesser-known movie Super Capers.
The center of this story is Marrow, also known derisively (and accurately), as Bonehead because he is an obnoxious bonehead. I did not like him at all, so I'm not about to continue read his story. He barely manages to get through his graduation test (who graduates at fourteen?!), because he has anger management issues which are simply not addressed!
Instead of him being paired with a capable mentor who can help him, he's blindly paired with Flex, a rip-off of Hancock, for no other reason than that the author evidently is blindly following a rigid plot here, which pairs opposites and has them become wonderful friends and super effective. Barf. At least I'm guessing that's what happens, and Flex probably dies, too. But I wasn't interested. I ditched this right after Flex appeared. I think if he'd started with more original characters and allowed them room to grow, and move and 'have their being', this could have been a much better story.
There are other rip-off heroes here too: Zero is merely Frozone from The Incredibles. Sapphire is Jean Grey from the X-men. Fantom is Superman. For some reason, I immediately felt suspicious from the start that Fantom might be some sort of villain in disguise. The super-powers these guys have - all derived form a comet impact - don't make any sense - but then super powers never do. The X-men super powers made no sense either, but at leas there was a deeper story there, one engaging, and attractive. This one was not.
The super villain Arachnis is essentially the Empress of the Racnoss from the Doctor Who Christmas episode The Runaway Bride. She's tediously quoting lines spoken by The Goblin from the original Spider-Man movie: 'itsy-bitsy spider. Yawn. I won't insult you by recommending this book. I'll do you the favor of warning you away from it.
