A series of mysteries. An explosion of truths. The Explosionist: Someone sets off a bomb outside fifteen-year-old Sophie's boarding school, but no one can figure out who. The Medium: Soothsayers and seance leaders are regular guests at her great-aunt's house in Scotland, but only one delivers a terrifying prophecy, directed at Sophie herself. The Murder: When the medium is found dead, Sophie and her friend Mikael know they must get to the bottom of these three mysteries in order to save themselves--even as the fate of all Europe hangs in the balance. Set in a time of subversive politics, homegrown terrorism, and rapidly changing alliances, The Explosionist is an extraordinarily accomplished debut novel for teens that delivers a glimpse of the world as it might have been--had one moment in history been altered.
