Ludwig does an amazing job taking us inside Ginny Moon's world. Ginny is living with her Forever Mom and Forever Dad when the imminent appearance of a Forever Baby Sister awakes memories of Ginny's Baby Doll. Was her Baby Doll a real baby? Will Ginny be able to reunite with her birth mother Gloria and make sure Baby Doll is okay? It was a frustrating read at times. You want to tell Ginny not to put glue on her teacher's chair. You want to advocate for Ginny, but ultimately she has to learn to do that for herself. Will she? Readers who enjoyed "The Curious Incident of the Dog In the Night" will also find this book to be a compelling read.
