Emily Books, the independent ebookstore and publisher cofounded by writer and former Gawker editor Emily Gould, has offered readers a subscription model since its launch in 2011: One ebook a month, for $13.99 a month or $159.99 a year. Now the company is taking that model to iOS, with a new reading app that also allows subscriptions. Emily Books largely focuses on “transgressive memoir and fiction,” usually written by women, that has never been published in digital format before.
