What works for me is to read non-factual books in hard copy and a fiction on kindle.  The two different modes of delivery help make a clear demarcation between the factual reading and the fiction reading;

Cosmos/ The Martian are my two first reading materials.

I wonder how many I will read within the next two months…….On Goodreads I have aimed for a minimum of 10 decent books to take me through to the end of 2018….4 months.  Anything else is a bonus!
