Evolutionary biologist Richard Dawkins has landed a book deal with HarperCollins’ Ecco imprint that traces his journey to becoming an atheist. Publication is set for fall 2014.

Dawkins has written eleven books, but The Selfish Gene and The God Delusion are his most influential titles. Brockman, Inc. agent John Brockman negotiated the deal for North American rights with executive editor Hilary Redmon.

Here’s more from the publisher: “Dawkins will tell the story of his own intellectual evolution, explaining how his groundbreaking work as a scientist led to his work as an atheist.”  (Photo via Lalla Ward)
