Diary of a Teenage Superhero. Teen Superheroes, #1

Teenagers with superpowers. A secret organization. Aliens on Earth. A weapon designed to destroy a city. Axel wakes up in a seedy hotel room with no memory of his past. A man lies dying on the floor next to him. Someone starts pounding at the door. Axel runs. While staying one step ahead of his pursuers, Axel begins to assemble the pieces of his life. He is the victim of an amazing experiment - he has been given incredible powers - and he is not alone.
An organization known only as The Agency has modified other teenagers too. Brodie is a master of martial arts. Ebony can transmute one substance into another. Dan controls metals with his mind. Chad creates fire and ice from nothing. They have been handed incredible powers to help the human race in times of crisis - and one of those times is now. A terrorist organization intends to fire a nuclear weapon at an American city.
Only this bunch of untried, untested teenage superheroes stands any chance of stopping it.
