fiction probably at least 15 years old

I read a book when I was working nights and it was about a couple who moved and their marriage was not good, she started to learn to meditate and during this she started to relive a past life of a woman who was something to do with robert the bruce. one of the women was called isobel.
It was a fairly trashy novel but i would like to read it again.

anyone out there recognise it?
I also think that the author may have had the name elizabeth in it.

That sounds like Barbara Erskine's Kingdom of Shadows.

have had a look and definately it - thanks very taking the time, am quite impressed i remembered it quite well!!
