The Voyager reading list is centered around the Post-Finale Series, which chronicles events following Voyager's return to the Alpha Quadrant. In addition to the other references noted below, several additional novels are connected due to recurring characters and various references in other books, or to other books. Others are connected by the six crossover series: Invasion! (which is referenced several times in the Lit-verse), Day of Honor (which shares references with several things in the Lit-verse), Double Helix (which ties into the New Frontier series), The Captain's Table (which is thematically connected to the Lit-verse spanning Tales From the Captain's Table), Section 31 (which ties into the DS9 Post-Finale Series), and Gateways (which ties into the DS9 Post-Finale Series and the New Frontier series.)
Two other short stories are connected, one from The Brave and the Bold duology (which ties into the Gorkon series) and one from Tales From the Captain's Table (which ties into the Post-Finale Series.) One comic is connected by the Telepathy War crossover event (which ties into the Starfleet Academy series.) One Lit-verse novel in another series crosses over with VOY- TOS: No Time Like the Past.
Also included are the stories from Distant Shores, which shares references with the Post-Finale Series and other works. Various references in parts of both the Wildstorm Star Trek Special and the anthology New Worlds, New Civilizations connect Voyager stories from both those works. Voyager figures only minorly in the Destiny trilogy, however because of its' story reshaping events they are included here.
Dark blue denotes the primary narrative. Read these for the bare bones story. Skip ahead to the next jumping-on-point to get current faster. Light blue denotes the expanded storyline. Read any or all of these to go a bit deeper. The grey denotes every other connected story from the entire Lit-verse, regardless of overall continuity. As always, not every reference to every other story is mentioned, just the one I chose as most important to show the expanding Lit-verse web.
