Viktoria Lloyd-Barlow's protagonist Sunday Forrester in All the Little Bird-Hearts is a mother, a gardener, a daughter-in-law, and an ex-wife whose world is ordered in specific ways that make sense to her alone. That is until new neighbor Vita moves in and delights in Sunday's neurodiversity such as only drinking liquids with bubbles and eating white foods on certain days. Sunday's friendship with Vita causes great delight that short summer but also a wedge in Sunday's relationship with her daughter. This book aches with longing, miscommunication, and the desire to be understood. A fascinating read.
