The Blue Little Monster is a friend of Rosa. You all know him from the previous books in the series, but now it's time to learn his story. Unlike Rosa, he is born in a colorful place where no one resembles another except for one characteristic: they are all their BEST. One little monster jumps high, another is strong and throws stones far away, the third has the loudest voice. But what happens when the Blue Little Monster realizes that he doesn't know what he is the BEST at? What is the skill in which he excels, and ultimately what can he do with those huge hands? A tender story that speaks about the virtue of empathy, respect, and the concept of coexistence, reminding us that what matters in a society is the moral excellence of its members.
