Maybe the best book on the subject of mediums, Hamilton expresses much humility and vulnerability, letting the reader intimately into his life in the first half of the book, while briefly tackling the history of mediums and the possible process mediums employ when sitting with clients in the second half. Both believers and true skeptics will appreciate how Tyson questions everything and takes nothing for granted, clearly spending time processing how grief can affect his beliefs and color his experiences. Hamilton offers valuable suggestions on how the investigation of this phenomena can move beyond the standstill that super psi and survival proponents are currently at.
