A well-judged balance between the academic, the informative and the anecdotal makes this an engaging, absorbing and accessible read. A book that brings together a plethora of current thinking and delivers a strong central message about our ability to grow as people - full of practical advice, tools for self-testing, excellent summaries and a clever device to answer the sceptics' questions. A book to make you think, but so full of optimism and positivity it's hard not to smile as well!
