Excellent book that traces the history of prose since Jaheliyya age until the Mamluki period. Since it is an overview, don't expect to find every prose writer. I was disappointed in how the Mamluki period was covered. It is as if the writer got tired of writing towards the end. But overall, it is a good guide that I highly recommend.
Maybe a bit too long for general non arabic speakers. Very little info about the figures while lots of repetative subjective descriptions. A good read though,
