The Final Warning - James Patterson
Max returns in a chilling adventure unlike any other. Safe havens for the six highly hunted winged kids have become increasingly hard to find, so the flock takes refuge in Antarctica with a team of environmentalists studying the effects of global warming. In this remote wilderness -- whether pursued by corrupt governments, bioengineered bad-guys, or the harsh forces of nature -- survival of the fittest takes a new twist!
