Having now finished Gavin Smith's War In Heaven - a book which I would ask anyone who likes a bit of military science fiction to read, and likewise the book it is a sequel to, Veteran - I must add to my previous statement:
The end of the book is superbly well written, and actually pretty much totally explains why Jakob was on the receiving end of some seriously unfair treatment. It doesn't make it okay - Morag was still being something of an unrelenting harridan - but her reaoning and her motives become crystal-clear.
Jut had to get that out there.
Go read Veteran and War In Heaven, both by Gavin Smith. I swear to god he's not paying me for this.
