/lit/ - Literature

I'm not native english but want to read in it to learn more and enjoy the books in its original language, the problem is that there are a lot of advanced words that I don't know and I don't want to be checking the translator on the PC all the time while reading.
I know that ereaders have a dictionary incorporated that translates or gives a definition of a word when you highlight it, but I need to know if that works on pirated books or only on the books you buy from their shop, also I was thinking on buying Kobo Libra 2, is it good? I don't want to buy Amazon shit but if it's way better I will consider it
