I was given a review copy for my 12 year old son to read. His thoughts:
Leon has the worst power you can have - he's a "glow." He can create light - everyone else has powers that are awesome, like becoming a hulk or flying or mindbending. Leon eventually learns how to get all the powers and when a plot for revenge goes bad, Leon has to make hard decisions about power and how to treat people.
This book was okay. I liked how Leon went from being the most picked on kid to being one of the most popular. I didn't like how Leon became the most powerful. I liked the writing style and probably would read something else by this author.
