You guys are taking this Brexit thing really seriously.
Walter Moers is a German writer best known for creating ‘Captain Bluebear’ in my all time favorite book. He has since written several fantastic novels based on the continent Zamonia. In some ways I think you could compare bis work and way of writing to Terry Pratchett’s.

Another German author that gave me lots of great hours of reading growing up is Cornelia Funke. For me it was mainly the book Dragonrider, but she is also well known for her Inkheart series and The Thief Lord.
I moved away from Swiftkey for the same reason and currently I’m pretty happy with what Heliboard has to offer. You can download it from F-Droid.
