I've gotten a lot more into short story compilations lately. A cop out; maybe. But it certainly fits into my schedule better; especially when there are long breaks between reading time. I get so caught up in so many different things that otherwise, I start to get confused about what fits in where :)
It's also a great opportunity to discover new authors! I only bring it up because, like you, it's hard for me to start a book and not commit to it. I've never read any of David Weber's work, but I will certainly keep it mind per your suggestion :)
