Stop the Sirens: Sirens of the Zombie Apocalypse, Book 3 by EE Isherwood

Exhausted after two weeks of rolling chaos since the sirens, Liam and his family prepare for their biggest challenge yet.

Fifteen-year-old Liam Peters starts his day in a muddy creek. The Air Force tried to wipe his subdivision off the map, but luck and fast feet helped him find refuge from the big bombs. When he looks up, he sees his whole life has been swept away by fire. And Grandma? He'd been successful getting her out of the city, and across suburbia, but she was snatched from him minutes prior to the attack. She'd gotten a one-way ticket to a brutal government facility set up to research the cure.

As a studious reader of zombie literature, Liam knows the dangers of being without shelter or direction during the zombie plague. He'd already been attacked by angry looters, malicious refugees, and hordes of zombies. His house had been riddled by a chain gun--twice--before the final bombs fell. He tried to look ahead, but saw little hope. He was bolstered by Victoria, but without Grandma by his side he felt defeated.

And yet, hope was out there. People were coming together to survive and help each other. One such group was at the Beaumont Boy Scout Reservation. It was an enclave of peace within the swirl of zombies and death engulfing all of metropolitan St. Louis. There Liam and his family might find a base from which to search for Grandma Marty.

As the trilogy concludes, Liam will learn the origin of the plague, the fate of Grandma, and whether a couple of teenagers have anything to look forward to in a world filled with zombies.
