Submerged by Anubis Enfield reviews
"Engineers log number 458. It's been almost half a year since the incident..." "Did you say Alterra?" "I don't talk to hallucinations." "I'm the Doctor and this is Donna." "You're joking, right?

Subvania by Laina Inverse reviews
It could almost be the adventure of a lifetime, if crash landing on an unknown world didn't come with so many caveats and addendums. For Trevor Belmont, Sypha Belnades, and Anna Torres, just surviving the crash of the Aurora was difficult enough. The alien planet clearly wants to kill them all... and down in the depths, a single survivor of a previous crash waits to die alone.
