First Steps for a Hero

Living on a farm in the north country of England in 1969, David Eldwick has finished high school and is looking forward to his new adult life. His enemy, Martin, lives on the farm next door. Martin is jealous of David and has made his life at school as unpleasant as possible.
Soon, Martin and his father will try to seize ownership of the Eldwick land by forcing David’s sister into an early marriage with Martin. David warns Martin off, but Martin wants Jenevieve and is determined to have her.
An enigmatic man comes to work on the Eldwick farm, and things begin to change. David discovers the stranger, the Captain, comes from Arrath, an Earth-like world, existing in a parallel universe. He teaches David the Arrathan way of self-defence, and David develops in skill and character.
At the end-of-summer ball, Martin kidnaps Jenevieve. Stronger now and more confident, David faces his adversary. He saves Jenevieve, and the Captain invites him to visit Arrath.
Now David learns that malevolent alien beings have also found their way to Earth, intending to infect it with evil. As he helps the Captain to deal with the dark invaders, he meets the greatest danger of his life, but he must overcome his fear and protect both Arrath and Earth.
What will be David’s path into his future? Does he truly believe the other universe exists and can affect the lives of people on Earth? Will he become a farmer or a warder of Arrath?
