The curse of historical fiction (book review of sorts)

To be honest, I read quite alot of fiction that is based around the zeitgeist of certain periods. Even though I read some classics in spare time, I also appreciate contemporary works of fiction set in the past. As an professionally trained historian I am fully aware that what I read is not history, but neither pure fiction since such books in some ways atleast claim to mirror the past to some extent. The latest such book I read was Helena von Zweigbergks 1979 - Johanna and Ingrid (sv. 1979 - Johanna och Ingrid) that is described as a family saga throughout the 20th century. Whilst this book do not claim to be "historical" in the sense that it is aiming at describing a certain time period fully correct, it still sets itself into a form of historical fiction. The book is part of a series were two titles have been released, with the previous one being set in the 1950's. What both books have in common is that they adress the role of women in Swedish society during the period...
