You can download Rodda's book here. You can also purchase a paper or Kindle copy of the book from Amazon.com.
Rodda depends on income from her book, but felt it was important enough to give it away. I suspect she'll see an increase in sales along with the free distribution.
Rodda's book seems to be selling well:
- Amazon Bestsellers Rank: #2,815 in Books (See Top 100 in Books)
- Amazon Bestsellers Rank: #2,451 Paid in Kindle Store (See Top 100 Paid in Kindle Store)
