Great book and a great movie it takes place with a boy and he watches his house burn to the ground and his family slaughtered by Vikings and he tries to hire assassins to kill them but he realizes later on that the man he hired has half of a dragons heart

It was a great book it had mystery a few scary parts and a lot of adventure parts and the books after it and the movies are great I‘d recommend it for people who like adventure

Really good book! Recommend it if you like action,adventure and graphic novels
