The Children of the Lost is a young adult fantasy novel by David Whitley. It is the sequel to his debut novel, The Midnight Charter, and was first published in 2010. It continues Mark and Lilly's journey after they are banished from Agora in the first book.
Concept
The book is set in a fantasy world called Agora, which is governed by an extreme form of capitalism. Anything can be bought and sold- including thoughts, ideas, emotions and ultimately people. Children are traded by their parents, and even on their twelfth birthday they are allowed to become traders themselves.
There is no money in Agora. Instead, people are ranked according to their reputation. It only takes a small rumour or wrongdoing to send even the most powerful merchant down to the bottom, where they normally become "debtors". With nothing left to trade, they are stuck at the bottom, with no means to climb back up the social hierarchy.
Agora is surrounded by walls. Nobody can enter the city, and nobody leave the city. The city itself is split into twelve districts, all named after Zodiac signs. The Director of Receipts watches over the city, and his Receivers police it.
