. Welcome to the board.
It's always great to see people newly interested in Trek lit.
Also, the "Vulcan's ..." series has been put because it sets up A Time To, Nemesis and Titan (or so I've heard).
said, it's not essential - you certainly don't need to have read it in order to read Titan
, A Time To...
, etc. (it was largely published after
they were, for one thing). The Vulcan's Soul
trilogy features a few characters who were important in those books, and shows how the Romulan situation post-DS9 became the Romulan situation we have in Nemesis
(and from there, Titan
). The continuity is rewarding, but it's not essential; it fills in some gaps in a way that should please a reader invested in the continuity details, but you don't need to read it .
