Barrington Stokes Books: https://www.barringtonstoke.co.uk
The concept behind Barrington Stokes books was that famous authors should write stories that were truly accessible to dyslexic readers of all ages. The idea is that the story content is aimed at people of particular chronological ages who have lower reading age. Thus they are able to access suitable literature for their age level. Dyslexic children helped to develop the font, and they are always printed on off-white paper. They are available in many bookshops.
