Well, you will have guessed it... another part is up and can be found at:
http://www.gundamwingtales.com/novel2/chapter2_part1_3.html Beta reader comments are outstanding.
This part again follows the series very closely. They did change the scene with Trowa getting rid of the pursuers however. Instead of riding on a nice motorbike, he goes on foot... and then murmur something about not raising too much of a commotion. This actually makes sense since they are (sort of) undercover. In the series, between a stolen motorbike, dumping said motorbike into the water and causing an accident, they would surely get a lot of attention. Not something they'd wish for...
Anyway, the conclusion of this: I do think the book makes more sense than the series here. :-)
Next chapter: Heero and Trowa head towards the South Pole while Relena finds out that Heero is still alive.
