I will finish all the manga in this franchise, someday. Maybe.
This two-volume series features what I consider to be one of the series' most interesting pairings. Even though I don't think Blood is a particularly good for Alice, this pairing tends to dig the deepest into her past, the memories she most wants to forget, and her private insecurities, since Blood looks so much like the tutor she fell in love with back in her own world, and who married her older sister instead.
Not that The Mad Hatter's Late Night Tea Party delves into any of that. For a series pairing up Alice and Blood, it was pretty mediocre and offered nothing new. I would also highly recommend that those new to Alice in the Country of Hearts (or any of the other countries) not start with this. It may be tempting to start with one of the shorter series, but it's a bad idea all around.
This is one of my post-vacation posts, so be aware that there are spoilers past this point.
