Magnus chase and the sword of summer - Rick Riordan

Surt laughed. 'The sword will be mine, boy.

You cannot change fate. I will reduce your world to cinders!'

I turned to face him. 'You're starting to aggravate me. I have to kill you now?

I walked into the wall of flames.

Wow, Magnus, you're probably thinking.

That was ... stupid!

Thanks, I have my moments.

I walked through the curtain of fire and smacked Surt in the head with my rusty sword. Because, you know, I always try to keep my promises.
