Resonant (Vault, 2020)

A decade has passed since the first Waves hit, unleashing humanity's darkest impulses and plunging the world into chaos. Paxton, a single father of three, must venture from the secluded haven they've built to restock the medicine his chronically-ill youngest son needs to survive. When the somewhat routine trip goes awry, Paxton and his children—now separated—will battle everything in their path to reunite.
