I probably should’ve answered that ask publicly in case anyone else was curious. The Star Trek Online story I liked is detailed in a novel called The Needs of the Many. The novel gives a little epilogue for pretty much all the characters from the three series in that era and takes everyone from the end of Nemesi to the launch of the video game. (It does have the supernova from the 2009 reboot mentioned in it, so this is a continuation of the original timeline.) I didn’t play the game but I liked it.
Not a Data centric book, though, his story is only covered in two chapters. However, if you’re fond of Jake Sisko it is definitely worth looking at since the concept of the book is “Jake Sisko interviews the Star Trek Universe.”
