If you are guys are into light fantasy similar to ASOIAF, check out the Mistborn Trilogy by Brandon Sanderson. The fantasy/magic factor is more prominent in these books but it's explained and fits in really well. The way it all comes together is rather amazing well thought out.
The one negative I can think of is that some of the dialogue is cliche at times but that didn't stop me from putting the book down haha. I'm about 3/4 done the last book.

Some of the reviews are pretty 'meh' on there and with good reason most times. It's only a trilogy (plus one standalone epilogue book) and a pretty quick read, so check it out if you're interested.
