The war of the givens
(Book)

It's been two years since the world collapsed in a sheet of light, obliterating everything on Earth...but not quite everyone. Saved from the apocalypse by three mysterious beings, sisters Hannah and Amanda Given were marked with silver bracelets, along with four other survivors from their native world, and transported to an entirely different Earth, a place where the fabric of time is manipulated by common household appliances. Afflicted with time-bending powers they never wanted, and on the run from unexpected new enemies, "the Silvers" embarked on a dangerous journey for survival across an alien America--a hunt for answers that bound the group like family while revealing the gravely sinister intentions of their so-called saviors.
