EDITED: There's a copyright on this book, so I can't ethically link it.
I gave it a quick read-through and was impressed that this author breaks out of the two patterns common in authoring books on rune magic.
A book on rune magick will have generally been written by nazis and have information but only for limited applications, or written by new age morons and be total bullshit.
Gundarsson does neither, and runs the full gamut of rune magic practices (as far as I can tell) in a brief 181 pages.
Gundarsson provides ample etymology and historical citation as well as citing sagas and idioms of the teutons, anglo saxons, and other groups that used the odinic arts.
There is very little padding to his words, and every one of his statements can be backed up by one other magickal discipline or another.
I found him easy to read, and very informative.
There is an equal amount of practical work and theory, he does take time to define his terms and tell us what everything means.
He draws conclusions based on esoteric texts pertaining to his topic, and gives his reasons for interpreting things the way he does.
Gundarsson's book covers Galdr sounds, writing wyrd, and the neccessary knowledge for Runemal. Coupled with a strong overview of the workings of each rune, this book conveys the bulk of the knowledge needed to walk the northern path.
The author also provides the reader with a more or less complete look at the elemental and cosmological models of the norse gothi.
I'd score this a perfect 10 simply because it stands out in its field.
