This isn't JoanK, it's PatH using Joan's computer. Any giggles you may hear coming from the west ar the two of us laughing together.
Babi, I forget whether you have read any Scalzi. The Old Men's War series is very good, but, especially the first one, have a lot of profanity, violence, and gory scenes of aliens and humans being splatted to bits. They get less and less violent as they go on, but should be read in order.
Agent to the Stars and Fuzzy Nation are lighthearted, funny, have very little gore, and a low profanity level.
Scalzi also wrote Your Hate Mail Will Be Graded, which is a collection of letters and his answers, bits from his blog, and other such miscellany. It's quite funny at times, but pretty miscellaneous.
One of his pieces of advice to young people wanting to become writers: "marry someone with a steady income". I'm guessing he doesn't need his wife's income now, but he's very grateful to her for her earlier support.
