All the information in the book To Hold The Sun is based on the most recent scientific research. My goal with the book was to present that information in and enjoyable and approachable manner. I hope one day to detail the research behind each section of the book. However I am currently engrossed in writing the sequel and it will have to wait. In the meantime all the information is available from other sources and I highly recommend that you look through my book reading list and also my podcast list. 

Warm regards
