Japanese novel recommendations

I recently passed (whew! barely!) the JLPT n2 exam. My worst section, by far, was the reading section because my reading skills are s l o w . There were two whole sections that I just didn't get to in the time given. I need practice if I'm going to get faster/better.

Can anyone recommend a good short novel for someone with intermediate Japanese reading skills? I'm not looking for manga, but maybe something light. I've read several of Murakami's novels (in English). Should I start with one of his shorter books in Japanese?

Would I be able to get this book at a US branch of Kinokuniya?

Thanks.

How about trying Kenji Miyazawa?

Hi, congratulations for passing the exam! I would like to recommend this book :キツネ山の夏休み (ジョイ・ストリート) https://www.amazon.co.jp/dp/4251061640/ref=cm_sw_r_cp_api_i_GcewCbK8PM...
Although this is a children book, I still read it sometime. It's easy to read, but the words in this book is beautiful. I think this author's choice of words is excellent. Good luck to your study! Hope this helps.

Thanks for the recommendations!
