"Though the moon had not yet set, the sky in the east was stained with light...."
What is that "though" doing there? These two states are not inherently contradictory! Either the moon is at a phase where it normally sets at or after dawn OR it isn't, and the moon shouldn't be up at first light, and this very mainstream litfic novel is about to turn magic realism on me. And I'm pretty sure THE ESSEX SERPENT isn't about to do that on page 355.
FAIL!
