Query: Slow-going at times, but a good read -- just like Moby Dick

It took me a while to get into this ambitious book, but I was glad I stuck with it.Naslund covers the time period of "Moby Dick" from the perspective of the woman who spent part of that time as Capt. Ahab's wife. This book touches on all manner of subjects, including slavery, women's roles in the 19th century, sexuality, mental illness and religion.At times I wondered where Naslund was going with all this, and I got a bit tired of the main character's modern-day judgments on her situation. But overall this book is worth reading. At its base is a good story, and that story deals with all the peripheral issues in a way that will keep you thinking.
