Avon will publish the debut novel by Kat French, an author on HarperCollins’ writing community Authonomy.
Undertaking Love will be published in summer 2014, following “impressive e-book sales and a wealth of 5-star reader reviews”, said Avon.
Editorial director Eleanor Dryden has also secured world rights from French for two further titles to be published in 2015 and 2016.
Dryden said: “There’s a fantastic, uplifting energy about Kat’s writing that had the Authonomy and Avon teams hooked straight away.
“Kat French is already a runaway self-publishing success, writing as Kitty French, with Kindle bestsellers Knight & Play, Knight & Stay and Knight and Day.
“We’re huge fans of Kat French across HarperCollins and we’re committed to building a stellar career for this exciting new voice in commercial women’s fiction.”
Scott Pack, director of digital content development at Authonomy, said: “We are always thrilled when one of our Authonomy discoveries goes on to secure a big deal with our colleagues. Kat has a big career ahead of her.”
HarperCollins launched Authonomy in 2008 as a platform for authors to publish their works online.
