Drinking Heavy Water

SECOND CONTACT

Aidan Redding''s entire goal for her time in this universe: behave. For once. Discovering seafaring aliens trashes that plan.

The aliens raise questions. Her co-workers raise more.

The answers explain it all. And ruin everything.

On a world where gravity changes every second, Redding finds herself involuntarily allied with a mathematician from Soviet Texas as she races to save not just herself but civilization.

Forget aliens. Nothing threatens Earth''s golden age so much as ordinary human beings.
