An excellent continuation of the original premise from late 1940 into 1941 especially in the Mediterranean.
Much wider deviations from our timeline, with the improved British Naval air arm beginning to have significant impact on the conduct of the war.
Still written mostly in the style of a time line rather than a novelization. However light up with welcome cameos based on the probable reaction of historical characters.
Well researched and plausible detail for air force and army issues as well as naval impact.
Perhaps more on the Battle of the Atlantic would have improved the balance of the picture.
As Churchill said it was the convoys that kept him awake at night. The impact of more long range ASW and naval air from CVLs, CVE and MACs would have been well worth the description
