Just finished it. I agree with all of you that this is landmark work. Although I am sure at some point someone will attempt it; it's difficult to argue with the blood spatter analysis, and where that leads. As a fairly committed Grassy Knoll guy, I must admit I always wondered why the massive damage to Kennedy's head was limited almost exclusively to the the right side. Logically, from that angle, the trajectory would have had the bullet cause more cross damage, at least to the back of the President's left side. The author very methodically, logically, explains why: using simple (or for this layman, not so simple...but understandable) mathematics, the 35 degree "trajectory cone", eliminates any shot landing from the Grassy Knoll.
I do have some (very) minor criticisms. The author goes a long way to discount the reliability of Dealey Plaza "ear witnesses", at least to the extent of determining the direction of the shots. Due to different elevations, reverberation and shock waves, echoes, etc...she concludes: "basing the locations of possible shooters solely on the statements of ear witnesses is categorically unreliable." Yet, at the end of the chapter "The Grassy Knoll Headshot", after convincingly arguing that the kill shot likely came from the SOUTH knoll area, she still felt the need to buttress her argument with ear witness testimony of hearing shots from that area. A devils's advocate would say she is trying to have it both ways.
Finally, I do hope in any future editions correct errors such as: repeated sentences, two or three sentences incorrect grammar wise, due to a missing word, etc. These are minor in themselves, but tend to take away ever slightly from the scholarly nature of this work.
That being said, Feister has once and for all put the lie to the single shooter from the rear myth; using unemotional, unarguable science. Facts are stubborn things....
