I respectfully disagree with all the authors. I remember there was a time when you you didn't have to wait six months to a year for the second part of a story (I.E. Romulan War) it was such a good book and I would have liked to have seen them released right after the first volume. The Typhon Pact series was released on a monthly basis. Why isn't this true of all the multi part stories?
As a long time follower of the Trek novels this is a deal breaker for me. I don't like buying a story where I have to wait a long period of time for part two. I am sure the authors are going to disagree with me. However in today's economic times, I'd like to finish a great story when I start it.
That hasn't really been consistent though; for example, we got all three Destiny books in a row, but in between Errand of Fury books 2 & 3, which were published a year apart.
I used to do what Therin suggested and just wait until the series was done and read them all back to back, mostly because I have a bad memory. (And I sometimes still do-- I'm doing that with Romulan War, in fact.) But with sources like wikipedia and Memory Beta now available, I usually just read the new books when they come out, and review the plot summary online before reading the next book to refresh my memory.
