I like books about writing, I like to feel the engine in my head start whenever I am challenged by a good writing prompt/idea / suggestion and clearly a good one will take you somewhere.
In this case, this book is so unoriginal, and the writing ideas in it are so silly that I am actually angry I payed for it. I don't need someone to tell me "Open today's newspaper and write about someone who's in the headlines" or "write a story based around a photograph", "Go to a gallery and pick a painting and write a story based around it" or "write about 5 thins that make you happy" arrrgh! it makes me mad!
Seriously, I could suggest a few: "look up at a cloud and write a poem" or "write about a lost puppy". In short, this book just glorifies her own approach and does not challenge your imagination at all.
I suggest this other book The 3 A.M. Epiphany: Uncommon Writing Exercises That Transform Your Fictionfor once, this is a book that challenges and exhausts you.
With Ms. Quigleys book I've fallen into the trap of the backcover
"...offering insights into the creative process".
Avoid this one.
