I really loved ASOIF and Night's watch. Both had really well designed, and that made for great gamebooks and a solid system.
Chronicle of Sorcery doesn't. Weighing in at a meager 47 pages, Chronicle of Sorcery hedges out the barest of the bare bones for a system. It gives a handful of "example lores," with no functional magic attached, three common lores, some rules for casting magic, and finally, five holdings. Furthermore, there's almost nothing to explain how to build balanced magic, leading to a situation where the Storyteller/GM has to make a judgement call on what works.
That's it. The common lores appear to be mostly written, but appear appear to have been designed with a book containing the rest of the example lores.
It lacks substance and anything that could be used to justify a five dollar pricetag. For what I got, I'd expect to pay .99 cents.
