What starts as a little sibling rivalry escalates to a life-or-death
threat. Can Edwin save his baby sister from the terrible dangers of the
Dead World?
Edwin really doesn't want to be a big brother. Forced to move house,
start a new school and make way for this unwelcome interloper in his
parents' affections, he feels like everything is chaos. But things might
not be as bad as he fears, as Edwin makes an unusual pen-pal, Lanthorne,
who introduces him to a strange world filled with dark secrets and
thrilling adventures.
This excitement seems safe until those secrets and adventures start to
intrude on Edwin's life and, more worryingly, on the life of his baby
sister. Can Edwin and Lanthorne work together to save Mandoline from the
evil Aunt Necra? And can they figure out why Lanthorne's family is so
divided, and what the terrible secret is that so many people seem to
know all about but refuse to share with Edwin?
