This is book number 7 in the Principles of Love series.
It's Love's final year at Hadley Hall - has she learned all she needs to get by? Who said senior year was simple? No longer a day student at Hadley Hall, Love Bukowski's about to move into the dorms - with none other than her archenemy, Lindsay Parrish. Love must deal with Lindsay's rules as head monitor; her handsome boyfriend, Charlie, returning to Harvard; and her ex Jacob giving her the cold shoulder. On the bright side, Love has a new look, a new feel, and best of all, she's going to be reunited with her mom and half-sister, Sadie. The boys of summer (or fall) may come and go, but Love's faith in family and her passion for writing stay steady. It may be the end of high school, but there will always be lessons in Love.
