I can only really narrow it down to two groups -
Articles of the Federation, A Singular Destiny, Full Circle, Unworthy, Paths of Disharmony, Rough Beasts of Empire/Plagues of Night/Raise The Dawn, The Never Ending Sacrifice, The Cold Equations trilogy, Over a Torrent Sea, Cast No Shadow, Unspoken Truth, The Department of Temporal Investigations duology, The Buried Age. And Vanguard.
The Spirit Walk duology, Before Dishonour, Zero Sum Game, Seize The Fire, The Folded World, The Vulcans Soul Trilogy, Troublesome Minds.
As you can see, there's a lot more 'hits' than 'misses'.
Probably 'Articles' as my favourite...
