> He was the perfect protagonist for a teenage boy: a coward, an underachiever, technically a wizard but only on a technicality, and frequently the most powerful spell in the universe was lodged in his head against his will. This will be familiar to anyone who has been sixteen.

s/frequently/initially

Also, how is a cowardly underachiever "the perfect protagonist for a teenage boy"?

"technically a wizard but only on a technicality" is obviously redundant

And what part of any of this is supposed to be familiar?

It's just a strange essay.
