Hello everyone, I just bought the first 4 volumes of Pokémon Adventures from Amazon, I shall receive them this week and it will take me about a month to read them (I don't have much time to read), it's a great opportunity for me since I haven't read any of the volumes before, I am planning on buying around 4-5 volumes each month until I catch the series, the problem is I already have all volumes up to 14 in my shopping cart, but can't seem to find the rest available on amazon. Could it be that from chapter 15 onwards it has a new name? I can't find them by Pokémon Adventures Vol. 15.

So my question is, where can I buy the rest of the volumes of Pokémon Adventures, and are they on amazon with a different name?
