underwhelmed . I've heard Al Lee speak before and thought that what he had to say was sensible. However, although I basically agree with his approach, I just cannot recommend his book. I found it to be too simplistic and to contain too much filler. There are many much better real estate investment books out there. Some specific complaints: * The margins are ridiculously wide; this book is much smaller than it seems. * Some of the appendixes (especially appendix A) contained too much filler. * much of the book is a painfully detailed description of fields in a spreadsheet. This sort of documentation should be directly in the spreadsheet (where it will be in sync with the latest version of the spreadsheet, etc... rather than in a book.) * When I heard Al speak in person he emphasized new homes and owning property in remote locations if needed (eg, owning property in Dallas even if one does not live there). The book did not really touch on either of these topics. That said, I did find a couple parts of this books to be useful or interesting. These are: * The chapter on Financial Statements was useful; In particular the ways that items for a rental property (like rents due, funds in lender held escrow accounts, property taxes due, etc...) show up on the statements was interesting. * The tip that you can begin advertising a property for rent before you have closed on it. * The tip that you can try to time your lease expiration dates to be during times when school is out. * The recommendation that you work with a property manager who is willing to / capable of helping you find properties to purchase

Plate Tectonics as told by those that assembled the theory . This is a highly informative account of both the ideas that led to the development of Plate Tectonic theory and the concepts of how the earth works. The book is engaging to read and is understandable to an audience at the level of Scientific American. I am using it as a required text in my course at Columbia University titled "Plate-tectonic theory and its geological corollaries". For those fascinated in how the human mind puts observations together to build ideas and then test them, this book is first rate. Each chapter is crafted by a different researcher describing his or her contribution to the over all theory. The reader encounters brilliant and original ideas discarded by peer review, scientists peeping over each other's shoulder, the rush to the goal line to publish first, competition for access to key data sets, a last minute conversion from the static earth perspective, and the thrill of exploration at sea. The authors presents a wonderful history in Chapter 1 of the intellectual passage from the first inkling of continental drift in the 16th century to the breakthrough in 1966-1968 of the full-blown theory of rigid lithosphere paving stones and narrow plate boundaries

Laurie Colwin's best ... I've read it half a dozen times . I am a huge fan of Laurie Colwin's writing, so I am baffled by the reviewers who didn't enjoy this book as much as I did. To me, her writing is sophisticated yet very comfortable. I can identify most with the main character in this particular book of hers as I also married a bit later in life and am trying to have a child despite being a little long in the tooth. The longings Jane Louise has for the domestic bliss that other people in her life seem to have so easily are all too familiar. This book will not hit you over the head with a message, and it does meander ... which is just like life for most of us. And I for one sometimes enjoy a book that doesn't leave me with a headache. Reading is so much like eating - balancing what's good for you with satisfying cravings for those things that aren't - and for me, Laurie Colwin's books are like hot tea with milk and sugar on a cold afternoon. Grown up, but sweet and comforting - they always hit the spot. And I still find myself in disbelief that there will be no more books by this great writer
