Like any good tonic, the books on this new list will invigorate and refresh. They are bold and ground-breaking, and at the same time they have real heart – a pick-me-up for mind and body.  Tonic authors will be leading experts in their fields with the empathy that comes from lived experience; and whether they have the expertise of life experience or academic credentials, their books will be warm, full of character and relevant to your everyday life.
