This is a great book for any of you that are already familiar with Transactional Analysis - but even if you are not, there is an overview section to get you on board.
What is interesting is that it does make clear arguments and uses a story telling device to illustrate points. Although, for the more advanced reader some of the stories do go on a little bit and verge on condecending, but I will forgive this as the author is clearly making an effort to make a complex subject accessable to all - not just Psychology students and Therapists.
If you are new to TA, I would recommend going for 'I'm OK, you're OK' and 'The Games people play' first as this book draws on these heavily and does help with context.
