In the following excerpt from Chapter 13, Maria Pilar pressures Maria to disclose information to her about Maria and Jordan's sexual encounter. Maria rightfully hesitates, finally choosing to disclose the simple bit of figurative overstatement—"the earth moved":
"Now you will tell me," Pilar told her. "Anything at all. You will see. Now you will tell me."
"The earth moved," Maria said, not looking at the woman. "Truly. It was a thing I cannot tell thee."
This metaphorical statement about the nature of Maria and Jordan's relationship emerges as an important motif in Chapter 13. Earlier on in the chapter, Jordan uses it to describe their lovemaking:
Suddenly, scaldingly, holdingly all nowhere gone and time absolutely still and they were both there, time having stopped and he felt the earth move out and away from under them.
The earth did not literally move from the force of Maria and Jordan's love; rather, the statement is an expression of the significance of their relationship. These two people have found solace and comfort in one another, despite all odds, in a wartime scenario inhospitable to life. Their experiences together, though brief, are not insignificant. If anything, the "earth moves" because of the couple's shortened time together. They value the small moments more, for their rarity in the face of near certain death.
