Alas, Trek novels are of a pretty mixed quality. I used to have all but when I moved I kept only the ones I liked best. Beware of "Wardrums" - it's absolutely awful. I can recommend "Kahless". It's actually 2 stories and jumps between 2 time frames which I find a bit unnerving. I tend to simply read all the odd-numbered chapters first and then the even-numbered ones, so that I get every time line without interruptions. Well written and rather thrilling, though.
Currently I read The Black Moth by Georgette Heyer. Nice little Regency novel with a happy end. Just the thing for long dark and cold winter evenings.
