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
Output:
POS
