Day tops Bookseller's first e-book ranking

Erotic writer Sylvia Day tops The Bookseller's first e-book ranking, the first ever e-book chart that includes publisher-supplied volume sales numbers. Entwined with You (Penguin) sold more than 200,000 digital copies in June, ahead even of its print sales; meaning that it becomes the first title to top both monthly lists having sold more digitally than in print.
