The title refers to the bow symbol used by Daniel, Joel, and Thacia in Chapter 7 that is also found in Psalms 18:34 in the Bible. Daniel has lived most of his life with hatred for the Romans. His hatred fuels his desire for revenge, and when an opportunity to get what he seeks presents itself through Rosh, he takes it and engages the Roman soldiers.
Daniel narrates to his friends how the Romans killed his parents, leaving his sister traumatized and forcing his grandmother to sell him into slavery in order to make ends meet. Daniel succeeds in recruiting both Joel and Thacia in his fight against the Romans. They use the bow symbol to communicate secretly. Understandably, the idea to use the symbol comes from King David through the Psalms.
Daniel and Joel take the symbolism literary, while Thacia asserts that the symbol demonstrates that it is God that gives people the ability to overcome their challenges. Daniel’s challenge is his hatred for the Romans, but through Jesus’ teachings he learns that love is a more powerful force that will “bend the bronze bow”.
Was it possible that only love could bend the bow of bronze? - Daniel, Chapter 24.
