The Shadow Walker is available on Amazon as part of a 4 for 3 special. Buy any four eligible items and get the cheapest one for free. I wasn’t made aware of the offer (I just happened to notice while checking out my books), so I have no idea when it ends. If you’ve been looking for a paperback copy and have a few other items on your wish list, this may be the perfect time to take the plunge. If all goes well, the sequels will be available (relatively) soon.
