Welcome Louisa! While English interaction here lets more of the community benefit from your threads, if your friend and her novel are in German, by all means do your *mapping* in German :-). We look forward to seeing what you devise - do please post some works in progress along the way. The commentary usually speeds your learning, and it's more interesting and instructive to see someone develop, than to have them say Hi, wait a long time, then display their polished proficiency :-).
