257 - 232 BBY
These two novels overlap each other a bit, so we are going to break down on to listen to them in order. First, we'll start with the flashbacks.
There are six flashbacks that occur in Into the Dark, which take place 25 years before the present-day events of these novels. Before starting these, I'd recommend listening to the Opening Credits first. Then this is how it goes from there:
1) Chapter 3; 21:16 - End of Chapter
2) Chapter 8; 0:00 - 10:18
3) Chapter 11; 19:30 - End of Chapter
4) Chapter 16; 21:48 - End of Chapter
5) Chapter 20; 21:16 - End of Chapter
6) Chapter 24; 25:37 - End of Chapter
Now on to the present day events:
1) Into the Dark: Prologue & Chapter 1
2) The Light of the Jedi: The Force is at Peace – End of Part 1
3) Into the Dark: Chapter 2 – 3 (stop at minute 21:18); then Ch. 4-5
4) The Light of the Jedi: Beginning of Part 2 – Chapter 27
5) Into the Dark: Chapter 6 & 7
6) The Light of the Jedi:Chapter 28 – End of Part 2
7) Into the Dark: Chapter 8 (start at minute 10:19) – Chapter 10
8) The Light of the Jedi: Part 3 – Chapter 43
9) Into the Dark: Chapter 11 – End of Book (skipping over remaining flashbacks)
10) The Light of the Jedi: Chapter 44
