Oh yes,.definitely Elizabeth Strout, love her books set in a little coastal village in Maine, USA.

Thank you for so many suggestions. I really appreciate your replies.

Rachel Hore.

I like Elizabeth Strout.

Thank you for these suggestions. I will certainly try these.

I also like Barbara Erskine, her books are historically set and full of interesting facts.

I haven't read any Lucinda Riley books, but enjoy Kate Morton's.
If it is dual timelines that you enjoy, Barbara Erskine does those, but more like timeslip/ghost stories.

Lucinda Riley had written several books besides the Seven Sisters, but you might already know that.
I agree on Kate Morton and also Kate Mosse is good.
Rosie Thomas writes in a similar vein, but all her novels seem to be very different from each other.

Thank you. Will try her!

I'd recommend Kate Morton, maybe try her first two, The Forgotten Garden and the House at Riverton. She writes in a slightly similar vein to Lucinda, generally two times frames. I've enjoyed both writers' books.
