Not academic or particularly enriching but clever and entertaining. Multiverse 'what if' stuff For the Civil War junkies - and I know we have at least a couple here on AE : The series later devolves into 'war porn' and I lost interest but the idea was cool and the first book or two decently engaging. Something like the 20th Maine and a companion New York light artillery regiment board a transport and wind up .... elsewhere. I really liked Taylor Anderson's Destroyermen series and have found these to still the withdrawal shakes until the next installment comes out next summer. TA contributes a Destroyermen related short story to the second book.
