Skyler, Scarlett, Amelia Grace, and Ellie all want impossible things. Skyler wants to keep playing softball even though her junior arthritis leaves her in constant pain. Scarlett wants to have a normal, healthy relationship, but she worries her emotional baggage will ruin it. Amelia Grace wants to be Christian and gay with no compromises, even while everyone at her church urges her to hide who she is. Ellie wants lifelong best-friendship like her mother has but always finds herself the outcast. When their moms force them together for the summer, the girls make a pact to achieve their "impossibles." Through four, distinct, alternating points of view, Allen (A Taxonomy of Love, 2018) presents diverse perspectives that will grab the heartstrings and pull them tight. Readers be warned, this story contains homophobia, self-harm, emotional abuse and manipulation, cyber bullying, and references to eating disorders and racism, but Allen handles all these topics genuinely and respectfully, simply adding to the realism of her characters.

When their mothers, who were sorority sisters, decide to reunite in South Carolina, four high school girls find themselves spending a summer together.All four girls are struggling with something: Scarlett is being pressured by her boyfriend to have sex; her twin, softball player Skyler, has arthritis and is unsure how to tell her parents that she wants to change her meds; Amelia Grace was looking forward to being a junior youth minister but after accidentally kissing a girl in front of her congregation feels pressure to hide part of who she is; and Jameelah, who goes by Ellie, is a tennis player who struggles with body image and belonging as a biracial (white/Indian) Muslim girl who passes for white. They all make a pact to "accomplish something impossible before the end of the summer." By that point they will learn more about themselves and one another and delve deeply into what they each want and what they must do to achieve it. The story alternates between each girl's first-person viewpoint. Readers learn about each teen's thoughts, personal ambitions, and fears as well as events from their pasts. Allen's well-rounded, realistic teen characters grow throughout, and she interlaces the story with complicated relationships that reveal each character's idea of friendship. Scarlett and Skyler are white and Jewish; Amelia Grace is also white.An engaging coming-of-age story. (Fiction. 14-18)

Summer at a lake: what could be better for four rising seniors? Except that the girls are being dragged to South Carolina by their mothers, old friends who rally around Scarlett and Skyler-s mom when her marriage hits the rocks. Scarlett, a recovering cutter, would rather be home with her boyfriend, but her twin, Skyler, is grateful for an excuse to miss summer softball. Amelia Grace, who accidentally kissed a girl in front of her church, is glad she isn-t being sent to conversion camp. And Ellie is a serious tennis player who could really use some friends; she-s hoping for some kind of -Ya-Ya Sisterhood club for female empowerment/shenanigans.- Allen (A Taxonomy of Love) tips her hat to the summer sisterhood tradition she-s working in while updating its inclusivity: Ellie is Muslim, Skyler has arthritis, and Amelia Grace wants a church that accepts her. The characters- alternating first-person voices are distinctive, the writing is sharp, and messages about honesty and being oneself add ballast to this satisfying multigenerational story of four girls finding the people they need.
