Isso é " Earthbound " de Joe Halderman.
A sinopse menciona um grupo de alienígenas (os "outros") se sentindo ameaçados pela frota da Terra:
The mysterious alien Others have prohibited humans from space travel-destroying Earth's fleet of starships in a display of unimaginable power. Now Carmen Dula, the first human to encounter Martians and then the mysterious Others, and her colleagues struggle to find a way, using nineteenthcentury technology, to reclaim the future that has been stolen from them.
e a revisão abaixo menciona a destruição da lua e a incapacidade dos dispositivos eletrônicos:
The story begins a few days after the group that was out to visit The Others, returns to an Earth on which 50 years have passed, and The Others have smashed the moon and disabled all electromechanical devices. Seriously, this book should have started with a synopsis of the earlier two books.
