Sylvia Day recently landed a book deal with Berkley Books for her self-published erotica novel, Bared to You. The publisher has launched a revised eBook edition and printed 500,000 copies of the novel for the June 15 trade paperback release.

So far, Vintage has sold over ten million copies of E. L. James‘ Fifty Shades of Grey, creating a booming new audience for erotica. Yesterday, Goodreads charted the spread of Fifty Shades among readers around the country, noting that Day’s novel had seen a significant spike on the social network for readers.

Here’s more from the publisher: “Shortly after its April 3rd release, Bared to You jumped into the list of top 40 bestselling eBooks at both Amazon and Barnes & Noble. The author is currently selling about 1,000 copies of Bared to You—every day! Bared to You is now a national bestseller, landing on both the New York Times and USA Today bestseller lists.”
