Square One publishes the highly prestigious and award winning Books Quarterly customer magazine for Waterstone's, the UK's leading book retailer.

The magazine has a remit to recommend books across all genres and to encourage Waterstone's customers to experiment with books and authors previously unknown to them.

Each issue contains a substantial amount of content, in the form of book reviews, contributed by dozens of Waterstone’s booksellers and external writers.

A spokesperson for Waterstone's said: “Square One's in-depth marketing knowledge and high-quality publishing expertise makes them the ideal media partner."
