This is a cute middle-grade mystery imagining the mischief Ada Byron Lovelace and Mary Godwin Shelley could have gotten into had they been contemporaries. With a supporting cast that includes Charles Dickens and Percy Shelley, this novel is an homage of sorts to the greatest creative minds of 19th-century England. A little silly and a little too modern in thinking for the time period, this is still a fun intro to the genre for young readers.
