I had some reservations going into this novel, because I've heard that it starts slow and (for some people) it doesn't pick up. BUTTTTTT -- I am so glad that I picked it up, finally! It sucked me in at about 75 pages, and didn't let go until the final sentence. 
 The novel runs parallel stories, one in present day with Erica and Beth Calcott, and another in the early 1900s with their great-grandmother Caroline. I found the earlier story to be more interesting, in a way, because of Caroline's daily life in the Western territory of the US. I was surprised at how arduous she found it, and her inability to let some things go and adjust to her new surroundings. The historical context of those chapters was new to me, and I'm glad Katherine Webb chose to use this time period and locale. 
 The present day story relied more heavily on a very lengthy, detailed exposition, which was harder for me to get into. Once we got closer to the heart of the story; though, I was totally hooked. The ending was unexpected (in a really good way), and I'm so glad I saw it through. Will definitely keep reading her books!
