What's a grand iOS app for reading comics and novels when I'm off the beaten path and don't want to drain my data?

Honestly, Manta has been a lifesaver on so many trips. I love getting lost in a good comic, especially on long bus journeys through places like Peru where the Wi-Fi is non-existent. What's proper useful is that you can download entire series to your phone. I've downloaded loads before heading off into rural areas, so I'm sorted for entertainment even when I'm miles away from civilization. Plus, it doesn't eat up your roaming data, which is always a massive concern when you're bouncing around different countries. The interface is easy to use, even after a few too many Chang beers in Thailand, and the selection is grand. Definitely a must-have for any travel blogger who loves a good story!
