Diary of a Bookseller is, and I mean this in the best possible way, chick lit for guys who watched Black Books (which, the diarist and titular bookseller, Shaun Bythell, did; he even sold a book to Dylan Moran).

The recurring characters (especially his employee, Nicky) become well-realized and you end the book with a much better grasp of the day to day to realities of the business, while still watching it romanticized.

Breezy, uplifting, sometimes, melancholy, and filling without being heavy. Like I said: a sort of chick lit for book people.
