Book

I have been asked to write one chapter for a book which these company might option, about Nord Ost, which i've been putting off for a while. Largely because i have too many other projects right now. Another reason is that this will mean going over all my materials on the subject, and i have probably the largest amount of it out of anyone, and this might be a little tough. Draining. I must get to it though. How does one rate their ongoing battles? Which ones are more important than others.
