As more of a Sense and Sensibility fan, I can't tell you the similarities between this and Pride And Prejudice but I enjoyed the book.

You get Georgiana Darcy in a very privileged high school. She has something happen her sophomore year that seemed to turn the whole school against her. She's determined to make things right this year. Though even the safest place she ever felt at this school, being as part of the marching band, she's feeling ostracized.

I liked her friendship+ with Avery. I knew the reasons he stayed her friend from a mile away, way before she realized it. 

I just love the band stuff. I wasn't in the band but was in Color Guard that does stuff with the band so it's very nostalgic for me in those scenes!
