I liked how the book was split into different parts of the writing process and different critically-acclaimed authors each took a chapter and offered their advice and tips on how to tackle each section.
The exercises are interesting and I’ve done a number. They do help alot in the writing process.
What didn’t work:
The only quibble I have with this is that it was abit too short and I wished that each chapter was a little longer. It would be nice to have something a lot more in-depth to chew for each section (i.e. more elaboration on the techniques, what should writers look out for etc).
