I just re-read "Old Man's War" by John Scalzi. I want to get the other books he wrote. I figure this is one of the well-written books I've read, like "Lance's War". There are other books where the subject matter holds me but they're not well written, they seem unfinished. "Fourth Protocol" was well done too.
"First Fast Draw" by Louis L'Amour, started that again. A few of these novels are ones I found at my dad's house (where my bro, sis-in-law, and 3 kids live too). They have some books I wouldn't have bought so I peruse the shelves when I'm there.
