"The Kingdom of Midnight" shows how Achille and Massimo complement each other's strengths and weaknesses, becoming one complete whole out of two imperfect halves. Mischievous but wonderfully imaginative, Achille leads Massimo into a world of adventure, while the introverted but clever Massimo reliably supports Achille along the way. Achille could never have built the Kingdom of Midnight alone, but together with Massimo, pooling their wisdom, they set off on a wonderful adventure and overcame moments of crisis. Having learned the true meaning of togetherness, Achille and Massimo now have nothing to fear on any adventure. Through this book, children will discover that true friends are not those who point out each other's shortcomings, but those who embrace and complete one another.
