The Bright of the Sky by Kay Kenyon is the story of Titus Quinn, a husband and father who found himself in another world after an accident crippled his spacecraft. Years later, he returns inexplicably to Earth with a bizarre tale that nobody believes until a team of scientists discovers the existence of that other world. Quinn is offered the chance to return, where he focuses on finding out what happened to his wife and daughter, only to discover that he isn't welcomed back.
This was a captivating science fiction novel, very well-written and imaginative. Though the reader is plunged into the story with little introduction and may struggle to make heads or tales of the situation in the beginning, he quickly becomes immersed in this fun and exciting tale. If you prefer stories full of rich prose and elegant description, this one isn't for you, but if you like a well-plotted novel that tests the moral fiber of likable characters, I recommend The Bright of the Sky. It's book 1 of The Entire and the Rose, though it does have a complete story arc and stands alone quite well.
