Mosquitoland by David Arnold
Hearing that her birth mother is sick back in Cleveland, Mim Malone ditches her father and step-mother in Mississippi and hops on a Greyhound bus to go see her. Along the way — a thousand-mile journey — Mim meets a colorful cast of characters, which help her face her own demons and come to terms with how she defines love, joy, and family.
Review from School Library Journal:
Mary Iris Malone, aka Mim, has moved from Cleveland to Mississippi (or Mosquitoland as Mim derisively calls it) with her father and new stepmother, who want her to forget her old life and even her mother. Mim is already struggling, but when she becomes convinced that her stepmother is keeping them apart, the teen steals money and hits the road to Cleveland to save her mother. The journey has bumps along the way—from a bus crash to unsavory characters. There are allies too, including romantic lead Beck and Walt, a homeless young man with Down syndrome. Mim grows on the trip and is forced to confront hard truths. Debut author Arnold's book is filled with some incredible moments of insight. The protagonist is a hard-edged narrator with a distinct voice. There is a lot for teens to admire and even savor-but there are also some deeply problematic elements. There's cultural appropriation: Mim uses lipstick to paint her face to soothe herself, calling it "war paint" and assuring readers that this is fine because she's "part" Cherokee. Walt's characterization veers close to stock, being only an inspiration for Mim. She and Beck have to take Walt to a veterinarian during a medical emergency. They joke that he is "kind of our pet." The revelations about Mim's mother's mental health, and her own mental health, arrive without clear foreshadowing and feel somewhat disjointed—particularly Mim's ultimate decision about her own medication.
