You often hear people say "That's not my type of thing" or "He wasn't my type" or "That's not a type of food I like." Whether you're talking about people, food or, yes, even books, everyone has a "type." Some people are romance types, some people are non-fiction types, some people are memoir types, science fiction, fantasy, young adult...there are many book types to choose from and many ways to pigeon hole yourself.
