My rating: 3 of 5 stars
A very useful little book, packed with information about where to target fillers and what sort of level and content you should aim for in order to have them published and, more importantly, get paid for them.
It is spoiled by some production errors such as a whole page being duplicated.
Fantastic value for money. A single paid filler will give a multiple return on investment.
Read the book and give it a go.
