as the novels are brilliant, could they do series 5 in book form, theres plenty of stuff to go off as said on the wiki page they could do more on the borg, the first borg queen, more on T'Pol, romulan war and the origin of the federation, theres lots to go off, could a series 5 novel series work....
Season 5 in the books pretty much is...
The Good That Men Do
The Romulan War: Beneath the Raptor's Wing
The Romulan War: To Brave the Storm
Season 6, so to speak, begins in just a few months with
Rise of the Federation: A Choice of Futures
Rise of the Federation: Tower of Babel
The novelverse told the origins of the Borg with the Destiny trilogy, which although set a few years after Nemesis, featured in part Captain Hernandez of NX-02 Columbia.
