I think your tastes are really different from mine, ronny, but I will agree with you that the TrekLit line these days is a little bit all over the place. Just in the last two months - I thought One Constant Star was super disappointing, I could not possibly be loving The Light Fantastic any more, and I didn't buy the TOS ebook at all.
I will say, though, that every year for the past few there's been at least one total jaw-dropper. TrekLit might be uneven now, but stunners still show up fairly often. Such as The Light Fantastic.
