Lately, the following:

Robert Little - The Revolutionist
Fiction, nicely done. I've read several books by Little and I think it's a decent read.
This is story told along the line of history from the Russian Revolution to Stalin's death. Part love affair, part spy novel, part thriller.

London has been informed.... - Reports by Auschwitz escapees
Chilling. Three reports by people who escaped from Auschwitz, when it was running at full power. It (partly) proves that the Allied forces already knew what was happening at the extermination camps in 1942/1943. Without doing anything about it.

Sebastian Haffner - Anmerkungen zu Hitler
Little book about Hitler. Interesting. It focusses on his achievements, successes, failures, mistakes and, ultimately, his treason. Haffner is a great historian and writer. I recommend his work.

Multatuli - Max Havelaar
Classic Dutch book. First time in 20 years I look at it.
