Yes i have read the book,its called Marianna shes an illustrator who buys a house that she saw when she was a child and felt drawn to,and as you say travels back in time.I really enjoyed it ,i think the author was Susannah Kearsley/Kersley.
If you like this type of book i can recommend Barbara Erskine The Kingdom of Shadows and one that i cant remember the name of.Daphne Du maurier wrote one that goes back in time called The House On the Strand.If you can recommend any to me it would be much appreciated
