Kevin J Anderson may be known to some fans as a Star Wars author. I’ve enjoyed his works with Brian Herbert in the Dune universe (The Prelude to Dune series is one of my favorites) . Kevin and Rebecca have released several other novels as well. The Crystal Doors is a young-adult fantasy trilogy and the authors are sending free signed copy (you only cover the shipping and handling).
I’ve picked up a copy for my family (I love being married to a geek and raising geek kids).
