Woody and June versus the Siege — Robert J. McCarter

Outnumbered, Four Thousand to Three Woody Beckman and June Medina defied the odds and found each other in post-zombie-apocalypse Arizona. No longer go-it-alone survivors, they now face the future together with something to lose. Each other. Stranded in a treehouse built high in a cell tower and surrounded by thousands of zombies, Woody, June, and Dallas face their greatest challenge yet. How do the  three of them escape four-thousand starving undead that want nothing more than to make a meal of them? Can Woody and June beat the odds and let their love flourish in a world of zombies and psychotic, petty, wannabe warlords? A story of adventure and love and taking things (even the apocalypse) in stride.
