I came across this while visiting another library in my system, and couldn't resist taking it home. I don't actually write chick lit, but there's enough overlap between that genre and my slice-of-life stories that the concept appealed, and I always enjoy reading more books about writing. I ended up really enjoying this, and I found it helpful in various ways.
The book breaks down the development of the genre and its various offshoots in a way that will be helpful for reader's advisory at the library, and the author shared interesting reflections about how to write chick lit, while also acknowledging and respecting the range of topics, settings, characters, and content norms that different authors choose between. The author summarizes general elements of the genre without being prescriptive, and even though this 2007 publication is quite dated now, almost all of the advice still applies.
The second half of the book focuses on the writing and publishing processes. I found this much less interesting, since most of it was general writing advice that I've read elsewhere numerous times, and very little of it was truly genre-specific. I would have been interested in more details directly about the genre, since I've never read a book like this before and wanted more unique content, but I'm glad that I got to read this. I read the only copy in my library system that is still circulating, and I'm thankful that I came across this when I did.
