Dear Mrs B.

Today we swam in a cenote, a type of sinkhole related to the asteroid that killed the dinosaurs, found only in the Yucatan. Amy didn’t want to go, afraid of the monsters that might lurk in those inky depths, but we convinced her.

I’m so sorry.

An enormous tentacle reached up and grabbed her before we knew what was happening, then disappeared with a splash and wave that nearly dashed us against the side. We tried to save her, but as deep as we dove, we saw no trace. Divers went in, but found no sign of Amy, the monster, or, weirdly, the bottom of the cenote. It’s a huge discovery for science, or so we say to console ourselves.

Best,

Emily
