In Vol. 3, Dark, my husband, astrophysicist, Dr. Martin Duncan and I have combined our talents to explore the theme of darkness, ranging from familiar topics like nightfall, dark skies and eclipses to much more exotic concepts like frozen stars and the mysterious dark matter and dark energy that seem to shape the structure and future evolution of our Universe.  But remember that within all the darkness there are bright stars and galaxies showing us the way. M.H. Duncan
