Im looking forward to the NEW one coming out in May as it seems very informative etc.
As for Sylvie's book I find the NO LAY OUT SPREAD is quite on to it and easy enough to answer SPECIFIC questions with KEY CARDS, however, the book can be very confusing and even if you did her course it isnt always helpful to understand the book. NOT AT ALL.
Also, I have interacted with her a number of times and she is not flexible with certain things, it is her way or no way at all when it comes to learning her methodology which is fair enough only some things are lacking with what she has written like she needs more in depth meanings to the "pairs", how to deal with "gay" questions and cards for "gay" people, the need for more in depth discussions with areas like: Astrology, Past Lives, Astral Projection etc.
However, if you can get passed the grammar mistakes and certain descriptions being a bit out, it is a good way to look at a different way to read the cards outside of the GT even though you might not quite get the gist of things at times as it isnt straight forward in her book to follow.
Personally, I cant wait for this book coming out in May 2013. Hope it is as good as I have seen written about it in one thread.
PS There is a thread on here somewhere about this book coming out soon, so check in the ORACLES area.
