It s not terribly unusual for a boy to have an imaginary friend, but Matthew s p
arents have to agree that his nicknamed Chocky is anything but ordinary. Why, Ch
ocky demands to know, are there twenty-four hours in a day? Why are there two se
xes? Why can t Matthew solve his math homework using a logical system like binar
y code? When the questions Chocky asks become too advanced and, frankly, too odd
for teachers to answer, Matthew s parents start to wonder if Chocky might be so
mething far stranger than a figment of their son s imagination.
