ay Hara is an ordinary young man growing up on the isolated planet of Erin. But Jay dreams of adventure and escapades and the legend of the lost “Godspeed“ drive which allowed humans to travel at faster-than-light speeds.
His life changes when he joins up with the seedy spacer Paddy Enderton and Captain Daniel Shaker. Captain Shaker is a charming but ruthless adventurer who inspires both fear and admiration in equal measure, and he and his questionable crew are joined by Jay as they race to find the legendary drive Jay Hara used to dream about.
Godspeed is a true coming-of-age tale told in the classic tradition of R.L. Stevenson's Treasure Island. A modern day pirate story, set among the stars.
