Grand Central Publishing plans to almost double  the number of titles from its Forever romance imprint this year.

Forever Yours, the company’s ebook-only imprint will also release more books.

The publisher will increase the number of romance titles from 64 last year, to 120 in 2013, expanding to 190 titles in 2014, according to a press release.

“With the romance audience more robust and diverse than at any other time, we are thrilled to expand our program to match the insatiable demand in the marketplace for romance books in every format available,” Forever Editor Beth de Guzman said in a release.

Grand Central usually only accepts agented submissions but Forever Yours is open to unagented submissions.

The manuscripts should be between 8,000 and 100,000 words in all romance sub-genres, including contemporary, romantic comedy, romantic suspense, western, historical, inspirational, paranormal, sci-fi/fantasy, futuristic, urban fantasy, steampunk, time-travel and erotica.

Amazon says its ebook sales rose a whopping 70 percent in 2012, but sales of traditional “treebooks” rose just 5 percent in December, the lowest growth rate ever in the online retailer’s 17-year history as a book seller.

In a statement, Amazon founder Jeff Bezos said, “We’re now seeing the transition we’ve been expecting. After 5 years, eBooks is a multi-billion dollar category for us and growing fast.” Amazon also says its total customer count is now over 200 million.

Just because print sales are way down at Amazon, that doesn’t necessarily mean treebooks are on their way out. At the New Jersey Romance Writers conference in October 2012, a panel of editors from major traditional publishing houses said overall ebook sales seemed to be leveling off and they expected regular treebooks to be around for a while.
