Remnants (Remnants Trilogy, Book 1)
by John Hennessy
The world ended in silence. No birds chirping. Dogs barking. Cars thrumming. No people going about their busy lives. After the aliens arrive, they clear the globe of every living animal, except for a few scattered bands of human survivors. Now Maggy, Darrel, and Félix embark on an expedition down the west coast, searching for safety in a landscape that promises only a gruesome death.
