I've just bought Jrustela and it's prety good, although it could be better.
It's an overview of the land of Jrustela and, as such, doesn't go into anything in any great depth, but covers a lot of things. Such are overviews and I'll not criticise or praise it for that.
There's a pretty picture omn the front of 2 ships being guided into port by an array of undines and some nice pictures inside. However, there is no single map of Jrustela, which is a gross error, in my book. If you have a source book, the first thing you need is a single map of the area covered. Bad Mongoose.
What's in it? Well, chapter by chapter:
History gives a fairly detailed history of Jrustela from the Godtime (Nothing is mentioned) through to the present day. These are arranged in sections covering different people or eras and contain a lot of things I had not read before. There is a Timeline and a List of Kings, which are noth useful. So, this is a pretty good chapter, not exessively detailed nor annoyingly brief, it gets the balance about right.
Gazetteer covers the geography and cities of Jrustela. There are sections on Geography&Travel, Cultures&Beliefs and Caste, then covers each of the Provinces and the towns and lands contained in each Province. Each city gets between a quarter and half a page and ends with a Reasons to Come Here sentence that summarises what is there and which is an excellent idea. Each Province is accompanied by an abysmal map, so dark it's almost unreadable and so disjointed it's hard to tie the maps together. So, Bad Mongoose for the maps and Good Mongoose for the content. The descriptions themselves are done third-party (Hooray!) and are very clear, with an awful amount of possible scenario hooks buried in the text.
Magic covers Jrusteli/Middle Sea/God learner magic and is split into several sections. The cleverly entitled God Learning 101 consists of a lecture by Haalabrim the Expositionist, a Jrusteli Scholar. Normally, I hate this kind of approach, preferring a factual third party description, but here it works and works well, I liked this section quite a lot. Here he goes into the different types of magic, how magic is used, how HeroQuesting is used and what it's effects are and so on. It has rules on Violating a Quest, Overpowering, Masking, Short Cuts, Shadowing, God Binding, Gate Switching and God Engineering, has 5 new spells for malipulating HeroQuests and rules for really blowing a HeroQuest and suffering a Backlash. So, it is a Godlearner Masterclass and very welcome it is, too. God Learner Orders contains four orders, each described with School Skills, Rune Spells, Sorcery Grimoire Spells and different levels of membership. These are good, but they blur into each other, so it's not always easy to see where one begins and where it ends. But, four orders is good, although I'd rather have seen a dozen here than four in three books, which I suspect will be the case.
Religion covers Godlearner religion in general. It has sections on The True Malkioni Church with 5 new Orders and New Spells, with 15 new spells. These are pretty good and each order has a shorrt description and membership details as above.
Politics isx a letter from an EWF spy detailing the politics of Jrustela and is as biased a view as can be expected. It does describe the politics of the various cities, but just touches on them and describes each one in terms of his own views, opinions and perceptions, which is really annoying, for me in any case.
Trade describes Jrusteli Trading in a very easy to understand way. There are rules for creating Trading Companies and examples of 4 Companies and 5 spells.
So, is it any good? Well, yes, actually, it is. The descriptions are clear, the book is easy to read and goes into enough depth to be useful but not too much to be boring. If it had a single map that was legible, it would be even better.
Should I buy it? Well, if you want to know about the Godlearner Orders or want to know how they handle HeroQuesting or want to know abou tthe cities and lands of Jrustela then yes. It has enough spells to be interesting to someone who collects spell descriptions.
What are it's weak points? Well, it has no single map, as I mentioned before. It could have done with more Orders, although it does have 9 so perhaps I am being unfair, it doesn't really cover the interior and only skips over the Earth Spirits, it doesn't mention the Aurelian Cult or the Breakwater cliffs or Volcano and, most importantly, IT DOESN'T HAVE A MAP OF THE WHOLE OF JRUSTELA and the maps it does have are so dark as to be virtually unreadable.
And, did I mention the maps? They're rubbish. And there's not a map of the whole of Jrustela, or did I mention that?
So, I'd give it an A-, Pretty Good, and a Buy It 85%, although if it had a good map of the whole of Jrustela and readable maps, I'd increase it to A and Buy It 95%, but it doesn't, so A- and Buy It 85%.
Bad Mongoose on the Maps.
