Star Trek Titan: Synthesis, by James Swallow
So far he's referenced Serenity and Star Wars.
The Titan books really are great Trek stories -- interpersonal, intergalactic, big science, big adventure, and all with the characters you know and love. The first "real" Titan book brought back the gigantic space jellyfish from Encounter at Farpoint, and this one brings back Minuet from 11001001 (that's not a spoiler; she's on the cover). Plus, it explains why the TriCobalt Device from the Voyager premiere was never used again.
