The dark journey continues in Volume 2 of The Tetrad Variant.
Alex and his friends have survived the apocalyptic aftermath of the blood moon, only to find themselves secluded, scared, and struggling to hold themselves together. Ella is desperate to find her estranged sister in a vampire infested city while others in her group wish to seek safer ground.
When Alex convinces the reluctant survivors to help Ella, they find themselves drawn closer to ground zero of the Tetrad variant, where nightmares come to life and no one is quite what they seem.
