I have a read a lot of superhero novels. There isn't a nerdier, more ridiculous premise, not even dragon fantasy or space opera, and also hardly a fantasy/sci-fi premise harder to do well as a book. Some authors just revel in the cheesiness of a four-color universe, others try to take them seriously, some tackle superheroes "scientifically" and make them just another science fiction concept.
Please Don't Tell My Parents I'm a Supervillain is more towards the four-color end of the spectrum, but it's not cheesy. Instead, it's written as if it takes place in a standard kid's superhero comic universe, and then plays it straight. Every genre convention is observed and taken seriously. Penelope Akk and her friends live in a world with an extensive superhero mythos of its own — there is magic (which Penelope's super-scientist dad refuses to acknowledge) and there was a secret alien invasion that all the heroes and villains know about but most of the "civilian" world does not, there are unspoken rules governing conduct between heroes and villains which most (but not all) of the villain observe, and in Northeast West Hollywood Middle School, there are numerous children of superheroes (and villains).
Penelope Akk's father is Brian Akk, a super-genius inventor, and her mother is the Auditor. Her friend Claire in the daughter of the retired super-seductress the Minx. Her friend Ray is... well, we don't learn much of anything about his parents in this book, though what little we do learn implies that they aren't good.
When Penelope's powers start to manifest, her parents are proud but tell her it will probably take four years for them to develop enough for her to become a full-fledged superhero. Little do they know that Penelope's gift for mad science is evolving at record speed, and soon Penelope is creating gadgets even her father couldn't conceive. When she concocts a formula that triggers Claire and Ray's powers, the three of them decide to get a start on their own superhero careers... except an ill-timed run-in with a sidekick who also happens to be their school's Mean Girl puts them on the wrong side of a public brawl, and suddenly the three of them are... villains!
Worse, they discover they're really good at it.
This is a fun, young adult romp with enough homage to classic superhero tropes to entertain even an adult (if you like superheroes). If your favorite character has always been the mad scientist/gadgeteer/supergenius type - the Reed Richards, the Tony Stark, the Lex Luthor - then this book is for you. Penelope's power has almost a mind of its own as she goes into a sort of trance state in which she starts building things that could only exist in a world with superhero physics, but she also turns out to have a genius for plotting and tactics. She and her friends go from one battle to the next, cleaning the clocks of much more experienced superheroes and supervillains, and making a name for themselves: The Inscrutable Machine.
Richard Robert's superhero universe is well-rendered - it has exactly the feel of a long-running comic book universe with its own history and continuity, established old timers, mighty powers whose names are spoken with awe, old battles and grudges, a big pool into which these three middle schoolers are now wading.
It seems like most of the negative reviewers complain that this book isn't "heroic" enough - Penelope and her friends stumble into being bad guys through mischance, but although they're never evil, and plan to "reform" eventually, they discover they kind of like making chumps out of heroes and proving they can hold their own against grown-ups. Thus, they embark on a number of schemes that are, let's face it, worse than criminal mischief, all while telling themselves they'll just go straight before their parents find out. This hardly makes them the noblest of "heroes" (though they remain rather adorable), but it does make them believable thirteen-year-olds, whose moral lobes haven't fully developed yet.
I actually thought this book treated its middle-school protagonists with surprising maturity - they act like kids, but kids on the threshold of adulthood. They are smart enough to compete with adults, but not wise enough to know when they shouldn't. They are starting to feel the rush of hormones, and you can tell that Claire is going to be big trouble when puberty really hits.
Mostly, though, the powers, the supers, and the battles were just awesome.
I give it 4.5 stars for pure fun, but your mileage will vary unless you are a superhero devotee like me. The book was a little bit bloated - there are a lot of extraneous scenes that were interesting but probably could have been cut. Also, the one point I got hung up on, challenging my suspension of disbelief even in a superhero novel, was the Inscrutable Machine's ability to fool their parents and keep their secret identities. Penelope's parents are both supergeniuses, and as a supervillain, she goes around calling herself "Bad Penny" - now come on!
But, I'm still rounding up to 5 stars because it hooked me hard enough to definitely buy the sequel!
