Among book readers, I think that there are two basic types. Those who read one book at a time, straight through, and those who have several books going at the same time. Both are very valid ways to read, but I don't think that either type really understands how the other type can read that way. I'm the later type, usually working on three, four, or five books at a time, reading a couple of chapters in one at lunch, a few pages in another while in the bathroom, several paragraphs in another waiting for the microwave to go ding. Right now, I'm stretched thinner than usual, with nine books going simultaneously:
Treason's River by Edwin Thomas, the third book in "the reluctant adventures of Lieutenant Martin Jerrold" series. Sort of a cross between the Aubrey/Maturin series and the Flashman series. Sort of. Not really up to the standards of either of those, but kind of addictive anyway.
Marilyn Chase's The Barbary Plague: The Black Death in San Francisco. Just starting on this, only ten pages into it so far.
Fateless by Imre Kertesz. Kertesz won a Nobel in 2000; Fateless is a novel based on his real-life imprisonment in Auschwitz.
North Callahan's biography of Carl Sandburg. A bit dry, but okay.
Natalie Goldberg's Writing Down the Bones, not really a nuts and bolts How to Write book, more of a Things to Think About Before You Start Writing book.
Ernest Hemingway's A Moveable Feast, more for a look at Paris in the twenties than because I particularly like Papa as a writer.
Just a Geek by Wil Wheaton. I'm about two-thirds done with it. Well worth checking out, even if you were never into Star Trek.
Peter Clark's Writing Tools: 50 Essential Strategies for Every Writer, Not really a Things to Think About Before You Start Writing book, more of a nuts and bolts How to Write book.
Baseball: A History of America's Favorite Game by George Vecsey. A wonderful little book. A must-read if you're a baseball fan.
