This is the weakest Y volume to date, with piles of secret origins that aren't insightful enough and two modest stories. Fortunately, the later story is the better of the two, hopefully suggesting that the comic is gaining momentum again, heading toward its finale.
Paper Dolls (#37-39). Yorick stops in Australia; hi-jinx ensue. I guess it's nice to see a story about the possibility of Yorick being outed, but there's overall not a lot of bite to this story, other than the nice opportunity to continue Beth's story [3+/5].
The Hour of our Death (#40). This one-off about Beth II actually has some depth to it, since we've come to care about both her and Hero. The church-related satire doesn't quite work, but the interactions between the two women are interesting [3+/5].
Button (#41). The backstory for 355. There's nothing particularly surprising here, but it's nice to learn a bit of her history [3+/5].
One Thousand Typewriters (#42). The backstory for Ampersand. There's one interesting reveal and one plot point, which makes it pretty decent [3+/5].
Kimono Dragons (#43-46). In Japan we get action, adventure, and tension, characters with their lives in danger, some hints about what caused the plague, and interesting dynamics between Yorick and 355. It's all around a good story that moves along nicely [4/5].
The Tin Man (#47). Dr. Mann's backstory is more interesting than most because because it's got emotional resonance. There's also more hints at the story of the plague and a pretty horrid modern situation [3+/5].
Gehenna (#48). Alter claims she's not a monster, but she is. I don't really care about the sob story that made her that way [2/5].
