   Summary

   Grace and Simon have finally started to develop something of a normal life on Erid despite the trauma the both of them have endured. Their relationship is going (Very)well, Simon has his own job, and Grace is keeping up with his never-ending scientific revelations on an alien planet.

   Enter: An amalgamation of alien biology, self experimentation, and a whole lot of guess work about to wedge itself into their hard earned peace.

   Sequel to Blood's Connections!
   (I'm going to try and keep this standalone but we'll have to see how it goes lol)
