The Lost Thing by Shaun TanRead about another entry on his list.
This book is a quest for the “Lost Thing” to find a place where it belongs. But perhaps even more, it is also a quest for meaning on the part of the reader. Ultimately it’s an allegory for conformity, and its dangers (I think), though since the point of the book is that we shouldn’t pigeonhole, looking for a definite meaning feels contrary to its spirit. So I suggest you just do what I did, and enjoy it. A lot.
