先占座

I was searching a little bit for it online, it's a very old book, I honestly doubt you would be able to find a ebook version of it since the original publisher doesn't even seem to have it online. I saw its listed price on amazon, quite expensive. My best bet is that maybe try to find a hard copy in a library if you want to get away from purchasing it.

Thanks for your advice
