This book is awesome. I wish they made something similar for other languages (actually French has a video series, French in Action, that is similar but not quite as effective as LLPSI).
That has a functioning link for the same content as the nina.coffee page tries to link to. There are several more French texts, as well as English, Italian, Spanish, and German.
There's an Icelandic text which isn't totally in Icelandic but, IIRC, is in the same vein as these. PDFs of it can also be found online pretty easily. I have not explored any languages beyond these as the two languages I'm interested in learning/practicing are Italian and Spanish, this content was sufficient for me.
