In the near future everyone lives in fear of the Horde-disease-riddled zombies who threaten to consume what's left of humanity. A girl named Hunter lost her family to them, like countless others. When strangers come to her village, claiming to control the Horde, Hunter and her people refuse to meet their demands-until the strangers steal their secret weapon; the young T. rex Hunter raised, named Ali. She is the only friend Hunter has left and nothing will stop her from rescuing the dinosaur...and maybe even destroying the Horde threatening their village once and for all. With a little help from a pack of utahraptors, she might even survive.
