Genetic engineer Noah Parker helped domesticate dragons for use as pets and deployed them for the U.S. military. Now his team is tasked with designing dragons to tackle invasive species and other ecological problems, in wildly diverse zones, from the hot deserts of America to frozen wastes of Antarctica. It’s no easy job, especially because government approval requires the dragons have built-in fail-safes to prevent them from reproducing in the wild. To Noah’s surprise, the approval also requires the presence of an onsite observer—who happens to be his former rival from graduate school. But as Noah and his dragons race around the globe to counter one environmental disaster after another, problems continue to pile up back home. The longer he is away, the more Noah risks losing the professional and personal worlds he has worked so hard to build . . .
