NO EASY DAY by Mark Owen is very badly written. You will find clauses that masquerade as sentences and misused words galore. The last 1/3 of the book is the actual story of the raid that killed OBL. The rest is a few chapters with "cliffhangers" to get you to keep reading and many chapters relating descriptions of how "glorious" the SEALs are with a special emphasis on how "glorious" Mark Owens is. If you believe all he writes you will wonder how any SEAL team was able to accomplish anything if he was not along.
In my copy the maps that would have made the raid clearer to understand all came AFTER the description of the events. A good editor would have moved those maps or given the page numbers of the maps in the prose. Actually a good editor would have asked him to re-write the book.
If you are really, really interested in SEAL training and the lead up to missions and you are willing to wade through a lot of gratuitous bragging to get to the mission itself, you might find this book enjoyable.
