Rebecca Yarros finishes the Fight & Glory series in much the same manner in which this series started -- with an emotional ode to the men and women who serve our country and the loved ones they leave behind. I had a pretty good idea what was going to happen in this story just from the touching dedication that left me a bit teary eyed. 
 Josh and Jagger get their orders to go to Afghanistan shortly after Josh, Ember, Jagger and Paisley have moved into adjoining condos. Told in alternating point of view, the precious days before Josh leaves are played out in aching detail, with Ember doing her best to keep her fears to herself, and Josh encouraging Ember to follow her own dreams and opportunities while he is gone. 
 A mission gone wrong has terrible consequences for the flyboys and their women. Josh and Ember's relationship is tested in a major way. Josh's sense of responsibility after the mission that changes all of their lives goes a bit haywire, and Ember's attempts to get through to him fail, highlighting a serious communication problem in a relationship that they may not be able to salvage. 
 There are a ton of feels in this book, so first of all, you might want to have a few tissues handy. There were times I wanted to knock Josh and Ember's heads together (especially Josh's). The tensions surrounding Josh's deployments are realistic and well done, illustrating that love doesn't solve all the conflicts or problems in a relationship but it can be the glue that holds things together while figuring it out. 
 I started this book late one evening and didn't put it down until the wee hours of the morning. I adored the final chapters of Hallowed Ground (really the entire book, but the first 30% and last 30% are just wonderful) and especially how Josh's best friend manages to put a big spotlight on everything Josh is in danger of losing. Go Jagger! 
 Hallowed Ground is a terrific end to this series and is a lovely tribute to our servicemen and their significant others. It highlights their sorrows and sacrifices along with the tremendous character and heart it takes to have this career. Knowing the author has personal experience in this life makes this story that much more rich and satisfying. Although I'm sad to see this series come to an end, the ending is just perfect and the decisions Ember and Josh make to get their HEA warmed my heart. 
 This series is definitely recommended.
