Danny is not appreciated in his family. His whole family are mages. They all have some sort of power. Danny has none until he realizes he is a gatemage. Gatemages are instantly killed for fear of what they can do and bring upon society.
Orson Scott Card is one of my favorite authors of Science Fiction. I loved the whole Ender's series and loved how futuristic and fantastical it was. The Lost Gate has all of that but for me, much more confusing. The idea of gates is cool but there were many times that I was totally lost, not understanding the story. Couldn't grasp whether it was set in the present, future or what.
