The Darkslayer: Wrath of the Royals (Book 1)

The Darkslayer: Wrath of the Royals (Book 1) - Craig Halloran At the start of this book, you think it's going to be similar to Fritz Leibers Fafhrd and Gray Mouser (big hulking warrior and slim thief as inseparable companions having adventures).

However, it soon turns out that the warrior is on a mission to destroy all the Underlings (the evil race in this particular novel), rarely listens to his friends and does what he pleases. Some of this is caused by his magic armour and weapons compelling him (or making his anger for the Underlings all consuming).

So, between his magic armour and the work of the omnipotent being who created the planet they are on, there's just mindless action, getting into a bind, and then a deus ex machina type of resolution before the next fight.

The author has tagged on a prequel at the end of the story to explain how the warrior got his magic weapons, but even before then, he didn't listen to the people he was with and got into a problem through just doing what he pleased.

I got this book as it was free on Amazon Kindle store, the other books in the series need to be bought, but based on this first one I won't be getting them.
