Song of Scarabaeus

Trained since childhood in advanced biocyph seed technology by the all-powerful Crib empire, Edie's mission is to terraform alien worlds while her masters bleed the outlawed Fringe populations dry. When renegade mercenaries kidnap Edie, she's not entirely sure it's a bad thing . . . until they leash her to a bodyguard, Finn—a former freedom fighter-turned-slave, beaten down but never broken. If Edie strays from Finn's side, he dies. If she doesn't cooperate, the pirates will kill them both.But Edie's abilities far surpass anything her enemies imagine. And now, with Finn as her only ally as the merciless Crib closes in, she'll have to prove it or die on the site of her only failure . . . a world called Scarabaeus.
