In the book The Secret Life of Bees, literally the quote means that a hive without a queen is a hive destined to die as the queen produces what is needed to live and continue reproducing. The hive has no future unless a new queen can be produced, and when she is, the hive is now alive and has possibilities again. Figuratively, think about what happens in Chapter 14. This chapter is where T Ray shows up looking for Lily and Rosaleen, the ones who had left him. His home had no queen bee nor workers to provide life and light and a future. Yet, he realizes that Lily is better off where she is and will blossom like a beehive with a new queen. So Lily settles in and blooms with the love and care of August who tells Lily, "We are enough."
