I built my first rifle using R.H. McCrory's
The Modern Kentucky Rifle, however there are better books out there now.
I only mention the old classic to illustrate that anyone can build a decent gun from almost any book, but some books are better than others.
I like both, The Gunsmith of Grenville County, and Shumway's, Recreating the American Longrifle, as both have their own approach to building.
If I were to choose only one book for a beginner, it would be The Gunsmith of Grenville County simply because it goes into more detail on drawing plans and layout than the other books.
