some people I emailed the link to also had problems. I then sent them the actual link I found in the magazine
http://www.harlequincelebrates.com/wdfreebook It goes to the same website mentioned above but this one includes The Horseman's Son. I should've posted this link to begin with-SORRY!!
As far as I know, this title is only available in PDF format. I tried to download it in epub format after finding the links that were posted in this thread but I kept getting error messages.
Hopefully the new link I posted works for you.
