If you read the book bruiser by neal shusterman, who is the hero of the story and why?

Bruiser is a teenage boy who is a unsociable person but later becomes a hero. Sixteen-year-old Tennyson fumes when he learns his twin sister, Bronte, is dating Bruiser, the guy voted Most Likely to Go to Jail, but Bronte insists Bruiser is misunderstood.

BTW Great Book.

Hope This Helps!    Have A Nice Day!!
