I've been reading @scalzi 's latest Old Man's War book, "The Shattering Peace". It's fantastic. I wasn't even sure I was going to buy it - the last few OMW books were less compelling to me, and I felt maybe it'd run its course, at least for me.
A funny thing about this book is that it is in addition to being a return-to-form for the OMW books, a kind of call back to one of Scalzi's earlier works that I really enjoyed, that being "The Android's Dream". I apparently really like kick-ass tales of space diplomats with unexpected talents.
