On his first day back to school in 7th grade, Xander Carson discovers a large black dragon blocking his locker. Soon he's seeing wyverns, wyrms, and other lizard creatures, but no one else seems to notice them at all. Was he going crazy? His life was tough enough already. His older brother - his best friend - had been killed in a car accident during the summer. And now dragons. Through an unlikely business deal with a nerd named Zayn, Xander discovers that there may be a reason he's seeing dragons - and these discerning creatures may be just what he needs to solve his paralyzing grief. But doing the wrong thing could make them disappear, exactly when he's growing to need them.
