Inertia
I feel like I could... TAKE ON THE WORLD!!
They are tricky to get into, I think the number of characters doesn't help which is something the Malazan series suffers from too.Yeah, made a start on Game of Thrones (bought some of the books years ago), but kind of finding it hard to get in to it. Tbh there's other epic fantasy out there that's better e.g. Janny Wurts' "Wars of Light and Shadow" and Robert Jordan's "Wheel of Time".
I've not read the Jenny Wurts series, but the wheel of time series drags something rotten in the middle which would stop me recommending it.
Wheel of time led me to Brandon sandersons mistborn stories which I can recommend though.
Oh for epic, its hard to beat Malazan
