When an evil artifact offers you the power to turn into a monster, agreeing would be stupid. Mirabelle isn't stupid. She also doesn't have much choice. Her friends all have super powers that let them go on exciting adventures. Mirabelle's super power is to be made of glass, and walking across a room is dangerous enough. But the shiny rock won't shut up, and to get rid of it, she has to use its powers against it. She does that carefully, because Mirabelle isn't stupid. Until Mirabelle falls in love, and love makes everyone stupid. Now supervillains and superheroes are fighting over four pieces of the Heart of Vermiel, and a girl who breaks if she runs has to collect them all, or be broken. She has to turn into a monster on the outside without turning into a monster on the inside. Somewhere in this mess there has to be an ending that lets her stay alive, stay a good person, and maybe get a chance to run, and be angry, and break things just once. Besides, how many girls can say their boyfriend is a dragon?

The superintelligent Tonika is grateful and full of plans to help Avery help others, but the more Avery helps, the more trouble she gets in. Her parents are worried.

Penelope Akk wants to be a superhero. She's got superhero parents. She's got the ultimate mad science power, filling her life with crazy gadgets even she doesn't understand. She has two super powered best friends. In middle school, the line between good and evil looks clear. In real life, nothing is that clear. All it takes is one hero's sidekick picking a fight, and Penny and her friends are labeled supervillains. In the process, Penny learns a hard lesson about villainy: She's good at it. Criminal masterminds, heroes in power armor, bottles of dragon blood, alien war drones, shape shifters and ghosts, no matter what the super powered world throws at her, Penny and her friends come out on top. They have to. If she can keep winning, maybe she can clear her name before her mom and dad find out.

What do you do when you have the wrong super powers? Magenta's older brother is a superhero. She's starting high school at the school where kids with powers go, including the famous Inscrutable Machine. Except, Magenta's powers are no good for fighting. Her potions are useful, not dangerous.

Suddenly she has a part-time job working for that same supervillain, who doesn't seem very villainous. She spends her afternoons buying mad science from smugglers, copying memories into a magic book, delivering messages to evil lawyers, and always, always, putting on a show. Soon, she's ducking heroes who want to save her from herself, and her best friends, who don't know the sidekick they're chasing is Magenta. Making sure her parents don't find out is the easy part.
