Furious

Reese and Emma are a young couple struggling to make ends meet while raising their four-year-old son. They've got a lot of love, but love doesn't pay the bills. Things only get worse when their house is burned to the ground during what appears to be an attempted robbery. When Reese asks his dad for help and a place for his family to stay, his dad offers only one, urgent reply.
"Run. Now! Don't go back to your house. Don't look back on your neighborhood. Something dark is coming. Something evil."
That's when Reese Little learns that trolls are real; that the Norse legends ...the scourge of Vikings ...ugly, giant trolls - are real. And, they want something that belongs to his family.
