There are two Star Trek books (and a third I anticipate will be out Tuesday) that I could get at Sony but I'm impatiently waiting to be released in LIT format.

I gave up waiting for the third (that came out in November!) in the ST: Destiny series that
still isn't in LIT because I HAD to finish the series.
I like the option to adjust the margins and add covers to books that don't come with the official covers. For me it's a far cry from where I was a year ago without a clue how to convert and fine tune LIT purchases.
