My apologies for not replying sooner. Yes, there are some first person accounts in the new book, but also a lot more 'hard research' than the first book. In many respects, it's a book without heroes. Neither of the two powers that occupied the Baltic States behaved well, and the citizens of the states themselves were forced to take sides in a fight that wasn't their own.
I'm currently working on my third book, about the Eastern Front again, but covering the fighting in 1914.
