Frostborn

"Thrones and Bones Frostborn , the first book in the Thrones and Bones trilogy by Lou Anders, is a fast-paced and fun adventure novel packed full of Norse and Norse-inspired mythology. Our two main characters are Karn and Thianna. Karn is obsessed with playing a strategy board game and not remotely interested in learning the skills needed to take over the family farm. Thianna is a frost giant in denial about her human heritage. By force of circumstance they need to team up against trolls and a gigantic winged serpent, not to mention wyvern-mounted soldiers, undead draugs and other assorted adversaries. Perfect for fans of How to Train Your Dragon as well as Percy Jackson ."
