Attack on Titan: Before the Fall, Vol. 2

The first volume was very promising, but this issue seals the deal. Mikasa is one of the best female characters in the genre (certainly my favourite), and this volume is all Mikasa! It's almost too bad that Eren comes back. This series would have been so groundbreaking if the first issue's classic ambitious, foolhardy young male protagonist ends up being eaten, and the series instead ends up being an action series starring an unstoppable young woman who sees titans as just a more obvious type of monster.
In this issue the world of the titans and the complexity of the characters' situation really opens up, and you start to see the depth of what this series can be. I watched some of the show before reading this series, so I know the twists are coming up, but it's really fun the second time around and just as gripping.
