Very interesting sequel. My favorite part was the hidenbach lecture. I have to admit that as much as I’m enjoying this series I get lost from time to time.

Love the line “get me that Tanguska crackpot”, but I (too) am slightly confused. (Because I have no clue who is speaking.)
.
Great addition though, not many people have ever heard of the Tunguska event.

hey now you should have a clue…only a clue though
