I really enjoyed the Old Man's War series so I was glad to pick this up as a free Audible download. Unfortunately I didn't enjoy it at all. It's not a story like the full novels, nor is it amusing as they often are; it's just an introspective monologue by one of the main characters. It is somewhat interesting insofar as it gives a little more detail about the life of an engineered soldier and provides some additional details to the OMW series, but really only for very die-hard fans - the kind who would read Tolkein's Silmarillion because they enjoyed The Hobbit. Another review said it felt rather like fan fiction and I have to agree.
