Purchasing Icelandic e-books is quite easy and it is relatively cheap for the value you get out of them as a student.
We highly recommend purchasing an e-book and an audiobook together and to use them together as a reading aid.
Note however that you will almost never encounter written Icelandic on a level below C1. Even childrens' books are written at a C1 level and use difficult vocabulary and phrases. For that reason you may as well want to spend your time reading regular books.
There are over 1,000 e-books and 300 downloadable audiobooks available on the website of the publishing house Forlagið. All e-books can also be purchased through Amazon for the Kindle.
The following is a list of some recommended books where both the e-book and the audiobook are available for download.
