About This Book
Nobody expects a sixth grader to solve a literary mystery—but Maggie and Jacob are about to prove everyone wrong. When an argument about who wrote Frankenstein sends them hurtling back to 1816 Switzerland, they land right in the middle of history’s most famous writers struggling with a scary story—and writer’s block. Can they help Mary Shelley create her monster before time runs out?
