I saw on Marlene's blog that John van der Kiste has written a short e-book (60,000 words with 6 illustrations) on Charlotte and Feo called Charlotte and Feodora: A troubled mother-daughter relationship in imperial Germany. It's only a $1.99. It's gotten mixed reviews (just 2 so far total though) but I took a leap since it's only $2. I just thought I'd pass it on to anyone looking for a quick royal book--provided they have an e-reader. It will be interesting, seeing as we hear about how hard it is to get non-NAOTMAA books published, if more authors go this route either with short books or full-length ones. Marlene has an article she wrote on the Gleichens available for download as well.
