I finished Vedanta, Heart of Hinduism, by Hans Torwesten a little while ago. Overall, I would recommend it, but there are some caveats.
First, the writing is very ambiguous at times - it is often not clear what a pronoun refers to for example. This can be irritating. There are also some really strange sentence constructions at times. The book was translated from German into English; perhaps the translator was a little too literal.
The first chapter of the book was confusing. The book is supposed to be an introduction/overview, but it assumes the reader knows a lot of things up front that most probably do not. In addition, the writing could be clearer.
Afterwards, things do improve quite a bit. Now and then though, especially near the end, the author assumes that the reader knows a lot about certain philosophers making the book hard to follow if you do not.
Despite these issues, the book does have its good points. It does give a pretty good overview of Vedanta philosophy - one of the six orthodox forms of Hundu philosophy. A reader would then know what parts are worth further study by him/her.
I did find Torwesten's comments near the end of the book interesting that concern merging the concepts of Vedanta with western/Christian views to get a more balanced whole. His take is that Vedanta offers so much on the big picture, but loses touch with what is going on here on Earth, while western/Christian philosophy tends to do the opposite in many ways. A happy medium would seem best. Makes sense to me.
I also like the cover of the book. Silly reason to read a book, but it is a nice cover.
In any case, if my caveats don't scare you off, give it a try. There is much in it of value.
