Goblin Slayer, Vol. 11 (light novel)

Female Merchant pays Goblin Slayer and his party a visit at their usual tavern with a proposal: Her next trade route will take her through the vast eastern desert where goblins now run rampant, and she would like the party to escort her. They accept her request, and the group promptly sets out for the arid eastern borderlands with its different cultures, brutal traps, and shadowy desert figures. How will our heroes fare in this unforgiving foreign territory...?
