Homecoming by Laura Lascarso

Welcome to Assburbia, population seven (and one cat).
Having left Promised Land and returned to the suburbs of South Carolina, Cipher, Joshua, and the gang are focused on fortifying their compound against Rabids and other undesirables. Without a cure in sight, they have to rely on each other now more than ever to survive. But even with all of their safety protocols in place, the Rabids are evolving.
When unexpected visitors arrive at the compound, Cipher and Joshua must confront their own prejudices and past deeds. Then the unthinkable happens–one of their own gets bitten–and the gang must put their faith in an unlikely ally in order to try and save a friend.
Time is ticking as more of the human race turns Rabid every day. How will our heroes maintain their humanity in face of such forces? How will they learn to do more than just survive?
