The numbering system also got a bit unwieldy once there were four different series. I mean, at the beginning of 1996, you had Star Trek novel #77, The Next Generation novel #38, Deep Space Nine novel #14, and Voyager novel #6.
which also gave us books like 'Star Trek: The Next Generation #41 Invasion Book 2 The Soldiers of Fear', which was obviously a sequel to 'Star Trek #79 Invasion! Book 1: First Strike'
