I'll be 100% honest here. If you're looking for the best grammar, punctuation, or writing style... this series is not for you.
If however what you want is action, adventure, excitement, and at times giddy laughter. Then this series was written for you.
I read a ton and there are some truly great authors out there. Michael Sisa has the potential to be one of them and I kid you not when I tell you that I drop other books I'm reading when his comes out because it's just a lot of fun and I can't wait to see what happens.
So. TLDR: Writing 6/10 Story 9/10 Fun had while reading 12/10
