At its best moments, James Haddock’s The Derelict Duty channels early Heinlein. His main character, Nic, has an exuberant voice that reminds me of the kids in Rocket Ship Galileo. Nic, the first-person narrator, becomes an orphan and loses an arm and a leg in the prologue when meteors destroy his family’s spacecraft. When next we see him, he is well adapted to his prosthetics and has earned an engineering degree. With the help of two high school friends, one an ace pilot and the other a software genius, he begins to revolutionize the asteroid mining industry and starts a long battle with the corporations who run the show in the belt.
On the negative side, things happen too quickly without enough engineering detail to be believable, but it was entertaining despite its stylistic lapses.
Here is a bit from the prologue that will let you know what you are in for: “‘Come on Nic, think! What do I need to do?’ I asked myself. I closed the hatch to Engineering to seal any leaks from the rest of the ship, then turned and had started back toward the bridge when there was an impact, a light flared and sparks showered from electrical equipment.”
It is no book for believers in the Oxford comma and the logical progression of tenses. ( )
