Last August a Berlin book launch event was cancelled unexpectedly.
By ‘a Berlin book launch event’ I mean ‘a book launch event that was going to be held in Berlin’. I say it like that just to be concise. Does it convey my meaning? And isn’t there anything wrong about its English? I am asking because there seems to me to be too many words in a row there, and I said maybe it is linguistically incorrect or not clear enough.
