The book is about the following characters:
- A guy who has flight, super strength and invulnerability to blunt damage.
- A super smart girl.
- A guy who has a black hole / wormhole in his abdomen.
- A girl with cat-like abilities.
- A girl who sticks to things.
It starts in a coffee shop with a poetry slam followed by a fight with an ice-wielding guy. It turns out that the kids are part of an experiment where a serum replaces the polio vaccine given to them as kids.
I've been looking for this book for years, if anyone could help that would be awesome.
