I'm now reading
Saving Mars, a freebie I picked up at Amazon -- probably based on a recommendation I saw here at MobileRead. I've read the first 6.5 chapters and I'm enjoying it very much.
I just can't figure out how the covers are pertinent. 6 books in the series and everyone of them has a lovely woman in an elegant gown. So far (first 6.5 chapters, remember) they're living on Mars and wearing "walk-out suits" -- environmental suits with helmets. Quite a long way from an evening gown.
