Threadworlds is set on a group of five planets that share a single orbit. The Earth-like worlds are teeming with life, and each has evolved its own unique intelligent species, in staggered states of technological progress. The epic adventure follows a chain reaction of scientific discoveries as they ripple from planet to planet. The hero of the story is Nova, a budding young scientist from a kangaroo-like species on the most primitive of the Threadworlds. Stubborn and brilliant, she lives out of step with her superstitious, oppressive empire, where girls are forbidden to read and write. But nothing can quell Nova’s passionate curiosity and awe of the universe. Her scientific pursuits sweep her up in a thrilling journey that links the fates of the five planets and unites the powers of their brightest minds in a pursuit for truth and progress.
