My AR book by JR

we had to read AR books in English. i couldn't find any that seemed interesting so i pick one i already read 3 years ago. its called Heir Apparent its about a girl who gets stuck in a virtual game and if she doesn't win she will get a fatal overload and die. Theres a riddle in the book that says "where was moses when the lights went out" post ur answers. when i see the correct answer ill post a comment with the name repeated many times good luck.
