Icon Books is to publish Darkness Visible, the "essential companion" to Philip Pullman's His Dark Materials trilogy.
Nicholas Tucker has penned the guide, to publish in July this year, three months before the first book in Pullman’s new series The Book of Dust will be released.
Darkness Visible is the "essential companion" to "one of the most popular YA series of all time" and accompanies a "hotly-anticipated" BBC adaptation of the series in 2017/18.
In this second revised edition of Darkness Visible, Tucker unpacks and examines the sources Pullman drew on for his series, from poets Milton and Blake to comic books and radio dramas.
The publisher said: "For while His Dark Materials can be enjoyed as a page-turning saga lit by an extraordinary imagination, it is also packed with literary references which raise important questions about our lives and even our ultimate place in the universe.
"Written for the general reader of whatever age, and including family photographs and illustrations, Darkness Visible offers a unique exploration of Pullman’s great work while discussing the controversies it has given rise to in the decade following its publication."
Icon will publish in B format paperback in July priced at £8.99.
