Irreversible

Alex had been reading these old books for hours; he was starting to get tired. He and Kiera had found the old spell that caused them to swap bodies so easily. They never suspected that the reversal spell wouldn’t be in the same book! They kept searching. Eventually, Kiera got tired and went home, but Alex kept looking. Now his eyes were getting heavy. However, if he read about the spell more carefully in the first book, he’d know that falling asleep would seal the spell, making the swap irreversible.
