Warriors [EPUB ebook] 

When twelve-year-old Jake Forrest’s mother gets a job in a new city, everything changes. He has to move away from the Iroquois reservation he’s lived on his entire life-away from his aunt and uncle, and away from the friends he plays lacrosse with. The lacrosse coach and players at his new school in Washington, D.C., believe that winning is everything, and they don’t know anything about the ways of his people. As Jake struggles to find a place where he truly belongs, tragedy strikes and he must find out who he really is. Can he find courage to face the warrior within-the warrior who values peace and leads other to more noble pursuits than outscoring the opposition?
