I'm new to language learning, and was wondering whether anyone has recommendations for a textbook for beginner-ish level Korean that is more substantive. Something that isn't just disjointed conversations and half-explained grammar rules. I'd be interested in something that integrates non-trivial discussions of grammar into the teaching of vocabulary and conversational practice.
The closest I've gotten to finding such a thing (at least in terms of feel, not exactly in terms of content) is , , or  but they don't quite fit the bill.
Anyways, thanks very much for any input!
