Whoops, sorry about that! I didn't read your post properly
I liked the book: 라인 쌈, 이렁게 가르쳐서 영어수업 대박내다 II. It's mainly a conversational activity book (with minor writing activities) but I really liked the variety of topics and I was able to change/adjust/add/extend whatever I needed to very easily. IOW, I basically used the topics and activities as planning and guides for paragraph/essay writing. My students were low-level so for a couple of them it was a bit of a struggle but overall they really liked it.
Just a heads-up: it is for Korean teachers so you can't check it out in Kidari, you'll have to find a Kyobo that stocks it if you want to have a look through it.
