The Alpha Plague Books in Order

When a disastrous outbreak erupts from the Alpha tower, Rhys has no survival plan. His immediate goal is reaching his son before the virus does, as the surrounding chaos forces him into a desperate struggle to protect his family.

Rhys returns to an infected city to rescue his ex-wife and best friend before the authorities incinerate it. Releasing the buildings' sealed shutters may offer escape, but it will also unleash fresh danger onto already chaotic streets.

After rescuing his ex-wife, Rhys discovers their son is missing from the meeting point. Following the boy's trail with her, he races against the spreading plague and a violent pursuer determined to destroy them.

Rhys and his companions escape the infected only to become trapped atop a shipping container surrounded by a vast horde. Temporary safety gives them a chance to rest, but survival depends on finding a way down without being overwhelmed.

Vicky and Flynn reach an underground settlement that appears to offer security after years of danger. As she tries to protect him, signs of a threat inside the community challenge her belief that they have finally found refuge.

After overthrowing a corrupt leader, Vicky helps govern the underground community that shelters Flynn. War with a brutal neighboring settlement forces her into command, making the group's survival depend on the fighting skills she hoped no longer to need.

Flynn believes Vicky abandoned him, unaware she was murdered by people running the community that keeps him safe. Discovering the truth will force him to choose between secure shelter and revenge in a hostile world beyond it.

Having escaped a ruthless self-appointed queen, Flynn and Rose decide to return and stop her advance on their former community. Building an army requires freeing her prisoners, a mission that risks recapture by an enemy unlikely to grant another escape.
