Thunder in May & Seelowe Nord
Just finished both these books by Andy Johnson.
Thunder in May - about the British Expeditionay Force in Belgium and France in WW2.
Seelowe Nord - an imaginery Nazi invasion of the England in 1940.
They are not literary classics but great action stories. I enjoyed Seelowe Nord the most - due to it being set in Yorkshire (my county).
If there is a weakness it's that a main character, Sargeant Jackson, is a bit too much of a superman.
