Hey. I havent read orcs so I can't compare, but I have read quicksilver rising and qiucksilver Zenith. There not bad but I get the impression that there nothing like orcs. The books are about a few main characters all with there own problems and agenda, but set in a backdrop of political upheaval as rebels try to find a new home. Theres plenty of magic and battle, I'd recommend them for a read.
