Day 2 ~ A book that you’ve read more than three times
Easily Dune by Frank Herbert (and the rest of the series as well.)
Day 3 ~ Your favourite series
Dune series by Frank Herbert and, of course, the other books in the series written by Brian Herbert and Kevin J. Anderson.
Millennium Trilogy by Stieg Larsson
And the three trilogies by Kylie Chan: Dark Heavens Trilogy, Journey to Wudang Trilogy, & Celestial Battle Trilogy. They are all one big series that is so AMAZING!
