Well, he mentions Marian Keyes and Sophie Kinsella. In the vein of Chick Lit/Romance mixtures is Shelly Fredman who has a series. Readers of the Evanovich Stephanie Plum series will notice a heavy influence.
There are four books (currently) in the series and the first three available on Amazon in Kindle format. The first is 99cents and the next two $2.99. I believe she's working on getting the 4th digital. She actually had built a solid enough fan base writing POD books to keep her writing at least and now she's trying to digitally publish. Sorry, I don't know if she publishes ePub anywhere.
