Devil in the Sky [EPUB ebook] 

The Hortas of Janus VI are the greatest miners in the galaxy, capable of burning through solid rock the way humanoids move through air. Recruited to help rebuild Bajor’s devastated mining industry, the Hortas could provide new hope for the planet’s struggling economy. But when Cardassian raiders abduct the Mother Horta, Commander Sisko finds himself stuck with twenty Horta eggs — and then the eggs begin to hatch… While Major Kira leads a desperate rescue mission deep into Cardassian space, Commander Sisko faces a ravaging mass of newborn Hortas — uncontrollable, indestructible, and eager to consume Deep Space Nine itself!
