One metaphor can be found in chapter 6 of Siobhan Dowd's The London Eye Mystery. The group of central characters have just arrived at the London Eye and are shocked to see how long the lines are. Since Salim is determined to ride the Eye, Aunt Glo and Mrs. Sparks decide to get coffee while the kids stand in line for tickets. Kat first questions if standing in line is really worth it because it will take them half an hour to buy tickets and "another half-hour to board" (48). When Kat expresses discouragement at how long it will take, Ted recites a metaphor once spoken in a sermon by Father Russell at their church:

Kat, an hour is a Drop in the Eternal Ocean of Time (48).

In saying this, Ted means that one hour is very, very small when compared to the eternal expanse of time, which makes Kat feel better about having to wait a whole hour. This is a perfect example of a metaphor because it draws a comparison between an hour and a drop of water in an ocean; a drop of water is also a very, very small in comparison to the entire ocean.
