At first I was like "damn, if Martin loves it, it must be good".
Then I thought about where I heard the name before. Oh. He's the guy who collaborated with GRRM on Hunter's Run and wrote the GOT comic book.
So you'll have to let us know how it is, due to me being skeptical. ha
He's likely my favourite contemporary writer of Fantasy. Here's my review of the first novel in this series, The Dragon's Path and an interview I conducted with him (which is also linked to in that wiki article you just posted.) He's also incredibly prolific, having published 3 novels last year, one of which is nominated for the Hugo Award for 'Best Novel,' Leviathan Wakes (co-authored with Ty Franck under the pseudonym "James S.A. Corey"). A high level of quality is found across all of the projects he works on.
tl;dr - He's fucking amazing.
