“Perfect Fifths” by Megan McCafferty — McCafferty’s Jessica Darling was a personal heroine, journaling all the same trivial high school woes smart, observant girls had back in ninth grade. Author Megan McCafferty has brought her snarky and relatable narrator back not once, twice, but now five times, due to popular demand. She’s aged along with her target demographic, now in her mid-20s, and “Perfect Fifths” concludes her romantic entanglements, career woes, and coming-of-age. So what if it might be considered YA (young adult) literature? Emotional ties call for a wrap-up!
