I've read a couple of Sharon Page's Regency era books, but this is a new direction for her. Not only is it set in the post World War I era, it's more women's fiction than romance. Her Regency books have much more explicit eroticism in them, so depending on your tastes, that may be a plus or a minus!
Although there is an HEA, along the way there is tragedy and multiple complications, I would call it more of an old-fashioned saga.
I think the author's prose doesn't flow as easily in this book as in the earlier historicals. And she overdid it a bit with the 1920's flapper cliches for her heroine, Zoe. Reckless and drives too fast, check; likes to frequent nightclubs and drink cocktails, check; wears short flapper dresses, check; smokes cigarettes, check!
None the less, I got caught up in the plot and the characters, and it certainly kept me turning the pages. So I give it 3 stars for good storytelling. If you like Downton Abbey type books, you'll enjoy it.
