Hello! so i am looking for this children's book that i had a few years back but i cant remember its name for the life of me. All i remember is the book( or book series?) had this girl make her own race car, explore a bunch of rooms she created in this like huge bush, and like make a makeshift phone with her friend with a tin can and some string. the art style was fancy nancy ish? It could have been released anywhere from the late 90's up to early 2010's. I cant for the life of me figure it out. Please help!
