If the plot of this book sounds familiar, you might remember it by its original title, Four Valentines in a Rainstorm.
Promising review: “Cornelia Augusta is a thoughtful main character who takes a surprise that life has given her and uses her time, energy, and imagination to make the most of it. These are wonderful traits to promote to children. Also the book doesn’t over-explain why Cornelia gave a particular valentine to a particular friend, so there is room for your little reader to come to her or his own conclusions. It also incorporates the themes of seizing the moment and accepting change (it only ever rains hearts once) which is a lovely life lesson as well.” —Stiletto
