as possible suggestions.
I suggest you read through a few of the "What Are Reading the Week of _____" threads, and see if any the books people have posted about sound interesting.
I read nothing BUT fiction, having never been interested in non-fiction, so I really have no idea what would appeal to a non-fiction fan. My personal favorite genre is Scandinavian crime fiction/police procedurals.
Come to think of it, I actually DO have a suggestion. Are you familiar with the 1986 assassination Swedich Prime Minister Olof Palme? There's an absolutely fabulous (imho) trilogy of books by Swedish author Leif GW Persson that are woven around that event. Fiction, yes, but referencing real historical events - not just the assassination of Palme, but the 1975 blowing up of the West German embassy in Stockholm by supporters of the Baader-Meinhof group. Woven throughout the trilogy are true historical events; Cold War political machinations, the rise of the Welfare State in Sweden, the long-lasting reverberations of WWII and Nazism in Europe, and more.
Maybe you'd find them interesting.
Here's the author's page on the Fantastic Fiction website: http://www.fantasticfiction.co.uk/p/leif-g-w-persson/
The three Olof Palme related books are listed at the top of his book list, as the "Story of a Crime" series:
1. Between Summer's Longing and Winter's End (2010)
2. Another Time, Another Life (2011)
3. Free Falling, As If in a Dream (2014)
If you decide to give them a try, I hope you'll come back to this group and let me know what you think of them.
