Those weird dreams Abby Kendrick has been having? Turns out they aren't dreams after all. They're out-of-body experiences, like the ones her cousin Logan is having. At first Abby has fun with her new ability, using it to spy on her neighborhood crush and spook a mean girl. But when Logan gets in trouble on the astral plane, the game changes, and Abby must bend the rules of out-of-body travel as she journeys to a distant realm. Her mission is a perilous one, and success is not guaranteed. Can she save Logan and find her way home again? Or will the cousins be lost forever on the astral plane?
