People love this book. It covers important issues, includes diverse characters (Latin@s, Black love interest, father figure with a disability) and characters cast against gender expectations (e.g., female principal and track coach, male school nurse), has non-linear elements, and strong symbolism to unpack (meticulous red lipstick and red nails). Too bad I didn't love it.
I was only confused by the now/two weeks ago time shift, didn't care for protagonist Romy, and thought the good characters (mother, mother's boyfriend, Romy's love interest, love interest's sister) were too good and the bad characters too bad, with the possible exception of a missing girl and the missing girl's boyfriend. The boyfriend is 95% jerk, but is redeemed by his genuine pain over his girlfriend having gone missing.
I'm glad for the people who love this book; it's nice to enjoy what you read. Too bad I'm in the "meh" camp.
