"Hawaii At War! On Guard in the Pacific, Book 2" is an 82 page, 10.5"x13.75" softcover edited by Riley H. Allen and published in 1943 by the Honolulu Star-Bulletin. By "Book 2" I believe they mean this is the second edition with updated information about the war effort. It includes a chronology, sections on major battles in the Pacific theater (Coral Sea Battle, Battles of Midway, Solomons and Aleutians) plus much more. There are many black-and-white photos.
