Warp Giants — Keith Robinson

Liam, Ant, and Madison have a busy weekend when the sleep writer predicts three separate events -- a flying saucer landing in the woods, a frightening mind-swapping experience, and a trip to a distant planet to save the last of a mysterious species known as the warp giants. The fourth book in the SLEEP WRITER series contains three interconnected novellas full of excitement, terror, and downright weirdness.
