When electronics importer Cara Leon goes missing, private investigator Sam Mujrif is hired by her sister to investigate. Cara is 8 times taller than Sam, but evidence soon points to players much smaller than either of them.

As Sam and his cross-scale colleagues pursue the case, it becomes apparent that Cara’s disappearance is linked to technology with the potential to reshape their whole society, and radically alter the balance of power between the scales.

@gregeganSF “In the universe of Scale, an electrically neutral atom might contain any mixture of leptons of different masses, so long as their total number, and hence the total negative charge, balances the positive charge of the nucleus.”

Is it in Google Play store yet? Also, does it come with an IQ upgrade?

@jgordon Yes, it’s in the Google Play store.

The story itself is very light on the science; it’s essentially a detective story / political thriller in an alternative universe Earth. So the background notes are there to satisfy people who want *much more* science than the novel contains.

@gregeganSF I read the physics note and learned about reduced mass and now I have to lie down.
@gregeganSF BTW, you might mention no DRM on book in Google Play. I was able to download my purchase and open in Apple Books app.
