The First Casualty by Mike Moscoe
The first Jump Universe book
An interesting military/SF book. We have point of view characters on both sides of the war, and indeed on both sides of the same battles between Unity (out in the newly settled colonies) and Earth (plus the heavily settled original colonies). And, unsurprisingly, a lot of untruths floating about.
It involves miners putting their skills to military use, highly educated recruits sent out as grunts, a "sour" jump (one you don't come back from), a marriage, a woman being shot for sedition and her family being billed for the bullet, field promotion, sharing a table to avoid empty seats, a wartime wedding, and more.
