The perfect picturebook for quarantine, In a Jar is a heartwarming story about Llewellyn and his friend Evelyn. The two collect all sorts of things to put in jars—both physical and abstract—so they remember all the things they do together. When Evelyn moves away, Llewellyn starts sending her portions of their collections by mail. Marcero's mixed media artwork uses texture and color in exciting and surprising ways throughout the story, and readers will have fun trying to count how many jars they can find on each page. A good reminder for readers of all ages of the simple ways we can connect, despite distance and its accompanying hardships.
