Your answer is going to be A, cuz i read the book and i know who wrote it.
Roach's tone is playful and conversational. Although her piece is very informative, it does not come across as cut-and-dry facts, but rather is enjoyable to read. For example, when Roach lists the apparently "yucky" food she's already eaten, she pokes fun at herself, saying "I am, yes, one of those annoying travelers who boast about the disgusting food they've lived to tell about." This self-awareness makes Roach seem like she is speaking directly to you, and makes you want to continue having a conversation with her.
It could be Digital Saber?????
