The Vancouver Sun had this to say about The Eyes of the Leopard.
Despite decades of successful publication and many professional honours, Hayden has surprisingly retained the sense of wonder that so often shrivels beneath the baleful glare of academic publishing. His prose is clear and direct, and he writes well about nature, character and the technical elements of Paleolithic survival. Think Jean Auel with less explicit sex. This is a book aimed at younger readers, but it will be read with delight by many adults as well.
