Colette Harris is the co-author of ‘PCOS’ and the ‘PCOS Diet Book’, patron of the UK's PCOS charity Verity, and editor of Health Plus magazine. She was diagnosed with PCOS in December 1996 and since then has been writing campaigning articles, speaking at hospital groups and at international health conferences to raise awareness of PCOS and the effects it has not only on women's health but their emotions and those of the people who support them. She's a passionate believer in the power of self help for managing PCOS through diet, exercise and lifestyle changes – 'Living well keeps my PCOS under control and helps me make sure it doesn't rule my life,' she says. Theresa Cheung was born into a family of psychics and astrologers. She gave her first public psychic reading at the age of 14 and has been involved in the serious study of the psychic world ever since. In addition to being a tarot reader, she has lectured and organised workshops on numerology, tarot, dreams and other aspects of the psychic world. Theresa has contributed to women's magazines such as Red, She and Here's Health as well as MBS magazines such as Fate and Fortune. She is the author of over 25 health, popular psychology and new age books including, Amazing You: Dreams (Hodder) and Teen Psychics (Adams Media).
