I got the code to pass through, but what I find difficult to comprehend is understanding why "book1" is GREATER than "book2"?
A Wrinkle in Time vs. A Brief History of Time
I understand it looks at the first character of the string, compares it, then moves to the next character. Having said that, shouldn't book2 be greater because "B" comes before "W"?
book_1 = "A Wrinkle in Time" book_2 = "A Brief History of Time" book_1 <=> book_2 1
