The craft book, Wonderbook by Jeff VanderMeer, provides numerous ways to look at the writing process.
Discuss the whole book or pick out a key concept the author sets out and formulate a response to that concept.
You may agree with the author; you may not. Let us know how your own work has benefited or might benefit from the craft element.
You should not set out to summarize the book, though referencing the text is recommended when commenting on specific ideas or passages.
