Zoe Sugg's books are definitely out there in digital formats, but the availability feels a bit scattershot depending on where you are and which platform you check. I've seen 'Girl Online' and its sequels as ebooks on major retailers like Amazon Kindle and Apple Books pretty consistently. Her non-fiction, like 'Girl: Love, Sex, Life, and Figuring It All Out,' pops up too. Audiobooks are a different story – they exist, narrated by different people, but I remember hunting for the audiobook of 'Girl Online' a while back and it wasn't on my usual subscription service. I ended up finding it on Audible, but only as a separate purchase, not part of the Plus catalog.
Her transition from blogging and vlogging to published author was huge at the time, so the publishers did make sure the books had wide digital release. It's just that the audiobook side might not have had the same perpetual push. If you're outside the main English-speaking markets, you might hit some regional licensing walls, which is always annoying. I'd say your best shot is to search directly on the platform you use. Sometimes the ebook is right there, but the audio version is weirdly absent or vice versa.
Honestly, I read 'Girl Online' as an ebook years ago. It was fine for that kind of light, breezy read. The audiobook experience, from the sample I heard, seemed to aim for that same youthful, chatty tone. It's not high literary fiction, so the digital format actually suits the casual, accessible vibe she's going for. If you're a fan of her YouTube persona, hearing someone else narrate it might feel a bit disconnected, but the text itself translates to screen reading just fine.
