Messenger directly connects the characters first seen in The Giver and Gathering Blue. Matty, first introduced in Gathering Blue, is the protagonist of Messenger. He is as spirited as he was in Gathering Blue, but perhaps a little tamer and wiser. Matty is curious about his community and the changes he sees in the people around him. In the beginning of the book he takes his job relaying messages very seriously, as he is one of the few who can pass through Forest unharmed. This book stands alone as a novel, focusing on serious themes such as pride, consumerism, exclusivity, global suffering, and community. Still, one of those most intriguing things about this book is seeing what became of characters like Jonas, Kira, and Christopher who were introduced in the first two books in The Giver Quartet.
