This is how he says you can help:
Of course, if you wanted to write an Amazon review of Balancing on the Edge of the World, that would not just help Salt but make me very happy indeed...
We need to keep Salt in the public eye. Here's how you can help. If you've bought a book from Salt and you enjoyed it please continue to support us by doing two important things (they're both free):
1. Firstly, tell your friends about the Salt title you enjoyed. Recommend it to them. Tell your friends on Twitter what you thought about it. Blog about it, if you like. Pass it on in anyway you can. Spread the word.
2. Secondly, please post a brief review of the book on Amazon to help the author. Amazon reviews do work.
Thank you for all your support. It really does matter.
Very best from me and Jen
