Well, it's obviously a fantasy religion, set on Erna where our decendants ended up stranded. But the morality is still there - who Gerald Tarrant IS is very interesting. The religions are mostly based around the use of the Fae, the energy that manifests according to cerebral activity in it (mostly subconscious thoughts). The fae prevents use of any technology, so it's either use the fae to your advantage, or tip toe round it. The 'one true god' scenario tip-toes, and the 'pagan' style smaller groups use it like druids. The main travelling party is made up of a representative of the church, a pagan-esque girl, and the vampire who shares the priest's views but is by his very being an adversary.
Would you like it.... there's no real romance, so no adult content of that nature, but the author seems to describe everything as 'sexual'. Other than that, there's nothing really icky or disturbing I don't think... fears becoming real because of the planet's energy... learning about various evolutions of a species.... big bad in the end... nothing that jumps out at me.
Here's a segment of my review of the first book:
'There are 3 things to take into account if you decide to read this book. Black Sun Rising plays out in first and foremost an epic adventure format. Think Tolkien, on a lesser scale/without the detail. Secondly, the book is intrinsically a combination of Sci-Fi and Fantasy, unless you like BOTH genres, this is not the book for you. While this book suited me down to the ground, I can understand why 99% of its reviews are less than praising. Thirdly, the book is most UNLIKE Tolkien-esque adventures insofar as the events in the book are secondary to the Philosophy behind them. Where LOTR was very much ‘good guys adventure and kill bad guys’, Black Sun Rising is about the gray area between good and evil. Notably, the gray area is portrayed by the most wonderfully sensitive comradary between two natural enemies. In a nutshell, if you like A) Dark Fantasy AND Sci-Fi, Philosophy and C) sword fighting adventure which is secondary to concept – then this is the book for you. It will appeal to a niche market but if you are in that market I promise you it is an infinitely rewarding read.'
