Raina knows quite well that she's being stared at.

If he's interested, the back of the book reads as follows:
By the author of the critically acclaimed Border Trilogy, Blood Meridian is an epic novel of the violence and depravity that attended America's westward expansion, brilliantly subverting the conventions of the Western novel and the mythology of the "Wild West." Based on historical events that took place on the Texas-Mexico border in the 1850s, it traces the fortunes of the Kid, a fourteen-year-old Tennesseean who stumbles into a nightmarish world where Indians are being murdered and the market for their scalps is thriving.

She lowers the book slightly so she can see over the top of it to scan the bar and see who's actually staring.
