I chose this list because i think it is interesting to see how we evolve over the years. looking at the most sold books for teens and there page numbers can really give me a look at how kids are today.
i learned from this experience that maybe teens have a shorter attention span because the most sold books average page numbers is 363 which is on the shorter side of books. It may not be the attention span but kids have a lot to do. for example school, homework, sports, and other clubs. A shorter read may be more appealing to teens because of less free time.
