I’m now on my 4th book, The Pearl Sister. It is better than the previous one I read, The Storm Sister, which was mainly set in Norway. I found all the different Norwegian names somewhat confusing, but also the actual story was not riveting.
They keep bringing up bits of the previous stories and the other sisters lives in subsequent episodes.
The books are readable, all follow a very similar pattern, present day sister interspersed with her past from 100 or so years ago.
All very attractive females, handsome men, the occasional villain, much angst, backed up by having had a millionaire adoptive father and they all seem to have sufficient money to follow the dream of finding their past.
