What’s the name of Zhenya’s island?

I’ve seen it translated 2 different ways, but I’m curious to know what the official translation of the name is?

I’ve been buying the novels as they’re coming out in English, but they’re currently on volume 2. I don’t remember if the island’s name came up in the early chapters and I don’t want to reread the novels until they’re completely available so I could binge read.
