If you want to read a substantial sample of 'The White Rajah' for free, there are excerpts on various web-sites. There's a short passage on JMS Books' own site and a rather longer one on Smashwords. Google Books also publish enormous chunks of it for free. All of these sites include links so that you can buy the whole book online if you decide you like it.
I hate trying to summarise a book in a few words. (If it can be summarised in a few words, what are the other 77,000 or so doing?) So I'm all in favour of excerpts. Smashwords gives the first 20% of the novel. If you read all that and decide you don't want to buy the rest, I've not done my job properly.
