"Katajavuori mixes history, natural sciences and sociology in an educative and entertaining way. For an amateur scientist who wants to ponder big questions, the book is like a full bag of pick 'n' mix candy.”

Tommi Aitio,



“Katajavuori weaves numerous exhilarating and stunning connections between humans, animals and plants… The huge amount of information that “The Matter of Death and Life” includes is wrapped up into a compelling popularized science book, spiced with black humour.”
