In DKS the Demon Wars book 'only' gives 3 skill points, rather than the 5 it did in the original release of Ego Draconis.
However, you should be able to read the book whichever trainer you picked, immediately after looting it (or later). If you can send it to the battle tower chest, try doing that and go take it out again.
Thanks I didn't expect a reply so quickly. I thought about doing that, but the book is in my quest items and I don't get the option, furthering my thinking that I bugged it somehow. I was able to use the potion of wisdom just fine which I guess would have a similar circumstance.
