Mind Power is well-organized, moving in a natural flow from the general to the specific, and eventually involving the reader directly through self-experiments. The language is accessible and clear, and a brief glossary provides short explanations of specific psychic terms. Collier comes across as a believer of psychic abilities, yet she constantly challenges readers to decide for themselves whether the information she presents is true. She achieves this balance by using a casual tone and by posing thought-provoking questions, particularly in the opening chapter. Unfortunately, many of the anecdotes and case studies included are not dated and do not provide any historical context. Nor are any citations given to back up the facts and quotes.

      While Collier's background as a psychotherapist lends authority to the book, the work lacks the bibliography, citations and index that would make it a useful tool for research. Nevertheless, Mind Power will appeal to young adults in grades 7 and up as a work of popular non-fiction for those interested in supernatural phenomena.
