The Dark Shadow Search on Google for a pdf file of this book. You can get it there.... I've read quite a few books that way.... Try out and let me know!! Otherwise check out the Amazon sale or something. I bought the whole do you in half the price!!
Serena You either buy it online (Amazon, Ebay, elsewhere) or borrow it from a friend (it is Kindle Lending Enabled, which allows one person to borrow it for 20 days) or from your local digital library.
