I'm slowly picking my way through Paradise Lost. That's tough to read at work, though, so I'll probably make it through another two or three Lee Child novels before I finish. They're real page-turners.
I was halfway through King's The Dark Tower series, but decided to take a break from that. They're good, but I can only handle so much fantasy before my common-sense filter kicks in.
I just finished Ambrose's Citizen Soldiers, which picks up after D-Day. Every bit as good as you'd expect.
