Yeah, it's real good. Jackel of Nar is the first, The Grand Design is the second, and The Saints of the Sword the third.
The originality (well, some tropes still play out) of the mashup genres in the trilogy are most excellent.
Jackel of Nar strikes a unique tone directly at the beginning, TGD literally blows the series into "this could be amazing, did that just happen," and then I think Marco choked on the finale... and his writing, in my opinion, (while possibly commercially better now) has gotten progressively worse. It's like he went from an aspiring Bakker to Gemmell, no offense to Gemmell as I grew up reading a lot of his stuff and loving it. Legend might have been one of the first books to have me crying like a baby.
