I have been reading them and they are shit. It would be nice if they even revealed something new or interesting about the various Chapters portrayed, but no. Generic bolter porn half the time, uninteresting dialogue the other half.
Some have been good. Some terribly bad and some just end so abruptly you're caught off guard and left wondering if your download of the book wasn't complete/corrupted.
I think the problem is that one thousand words is just not enough for a Space Marine story. They should have made the limit 4-5k.
Any thoughts on the ones by Thorpe, Similie and McNeil? I can't risk wasting money on those authors. They haven't redeemed themselves yet.
