* The "Crossing" itself: The literal crossing of the river represents a larger metaphorical crossing. It symbolizes leaving behind the familiar and safe in the Outer Provinces for the unknown and potentially dangerous world of the Capitol. It represents a transition into adulthood and the acceptance of responsibility.
* The "Flock" and "Birds": The characters in "Crossed" are often referred to as "birds" and their community as a "flock." This metaphor highlights the sense of community and the close-knit nature of their society. However, it also suggests a lack of individuality and a sense of being controlled.
* The "Net" and "Entanglement": The physical net used to capture birds is a metaphor for the social and political control exerted by the Capitol. The characters are "entangled" in this net, unable to break free from the limitations imposed upon them.
* The "Clock" and "Time": The constant presence of the "clock" in "Crossed" and its influence on the characters' lives represents the relentless pressure and control exerted by the Capitol. It symbolizes the limited freedom they have and the fear of being "caught" outside of the allowed time.
These are just a few examples, and the interpretation of metaphors is subjective. It's important to note that Condie uses more symbolism and allegory to explore themes like control, conformity, and rebellion. The novel focuses on creating a dystopian world and exploring the consequences of obedience and resistance.
