When college student Alex Drummond takes a summer job as research assistant to eccentric cryptozoologist Thaddeus Bruckner, he’s not sure what to expect. He certainly doesn’t foresee babysitting the egg of a Titanis walleri, the massive avian predator that once ruled southern Texas. But after Dr. Bruckner’s experiments in “wormhole dilation” work a little too well, that’s exactly the role he’s stuck with. And when the newly-hatched Titanis is abducted, things get even wilder, as its vengeful parents tear through a wormhole to wreak havoc in the Lone Star State. Bruckner and Alex are forced to play monster wranglers in a desperate effort to get the rampaging Terror Birds back to the Pliocene and avert catastrophe!
