Sorry, but this book is flawed in many ways, not the least of which is the fact that all of the anecdotal stories are similar, making this a slog to read.
But when the author of the book professes to believe in psychics, mediums, intuitive healers, and hands-on energy healing, he lost me.
There's enough woo surrounding the HSP trait already on the Internet. To see it published in a book by a supposedly reputable author is appalling.
