In Zeroes we were introduced to a group of teens with unusual, mostly subtle superpowers who find themselves in an increasing amount of trouble with both drug dealers and the police, using the very powers that got them into trouble in the first place to get them out again. I liked the novel a lot, so when I found out about the sequel, I was very excited.
In general, I like my superhero stories epic and idealistic. The "fresh take on superheroes" idea is getting pretty worn out, and I've grown tired of people deconstructing superheroes and trying to apply the genre to "real life." But Zeroes pulls it off and really does seem fresh and original, even when relying on some standard clichés of both superhero and YA fiction.
