I recently started reading book 1 of the Titan series and am already drawn into the optimism of Riker, Troi, and co. on beginning their new era of exploration. I just had one question regarding what I believe to be a reference to the "A Time to..." series which I did not read. It mentions that Riker's last year on the Enterprise was a difficult one. It almost implies to me that the Enterprise was not a very welcoming environment to him at this time and this was partly responsible for him leaving for Titan. I wonder if someone could explain the nature of this feeling of Riker's. Thanks!
