YMMV: The Lost Fleet
- Critical Research Failure: In Leviathan it is confirmed that Jump Drives can't safely reach binary star systems. Padronis, a white dwarf star the fleet passes through, is stated to occasionally go nova. This doesn't happen unless a white dwarf has a companion star for the hydrogen to come from.
- Nightmare Fuel: Everything to do with Europa.
- Tear Jerker: Finding out why the Dancers need to get to Kansas in Guardian.
