Lori Olding - The Origami Nun [Kindle azw3]

Seven-year old Ruth can't speak, but she can certainly think. She knows her birthday is going to be good as her beloved great-aunt has exciting plans for her. What she doesn't expect is a magical paper nun, an encounter with a bully who may not be what she seems or a school day to remember. Because when her special day is over, Ruth is in for some VERY big surprises.
