Actualitte reports that eBookezvous opened with a limited selection of French and translated works. It's supported by an Android app, and an iOS app is in the works. The site is also planning to add audiobooks.
Numilog is described as the leading ebook distributor for France, and it has deals with 500 publishers and offers a catalog of 170,000 titles which is distributed through a network of 150 retailers.
Not being able to read French, I can't tell you how many titles are offered on Numilog's new site, but I do know that the new site has its work cut out for it. Both Kindle and Nook have well established French language sections, with the Nook Store carrying a surprising 255 thousand titles to the Kindle Store's 65 thousand. Both of those stores have an English language interface, while eBookezvous is in French, but I'm not sure that alone is enough to recommend it.
