This series dissects the science behind folklore's scariest monsters and most spine-chilling powers! The text shares the history behind each creature and myth: Why did people invent these monsters and powers, believe in them, or claim to have seen or possess them? Each title examines the scientific possibility that the topic could exist. Readers are prompted to make their own hypothesis: could [ghosts/vampires/psychic powers] exist? Aligned to Common Core Standards and correlated to state standards. A&D Xtreme is an imprint of Abdo Publishing, a division of ABDO.
