I don't think it's 嗎, looks more like 吧 to me, which also has question like properties. But you're definitely right about the question mark not being included until much later. The character alone says it's a question.

Congratulations! Bamazon had a glitch and is sending out daily shipments of the last thing you bought. Customer service can’t stop it. What is it?
I just started reading P. Djeli Clark's A Master of Djinn but I'm not far enough in to know if I'll really like it. So far so good, though.
