  Summary

  Jason Grace is tired of being a demigod. Almost dying was the final straw.
  Using the name of a dead friend, he goes on to become disgraced molecular biologist Dr. Ryland Grace.

  Cue the plot of Project Hail Mary but actually it's in chronological order instead of jumping from ship to memories because we felt like it and also Grace isn't just a normal person, but a demigod son of Jupiter and what changes because of that fact.
