Jax is a lone mine operator on a desolate planet with an unbreathable atmosphere where the only companionship is with his artificial intelligence and a series of mining robots that keep the facility processing ore. Turns out the ore is explosive. Just about everything else is in "Deeper," a novel by Glenn Haddix and part of the universe created by sci-fi legend Ryk Brown. Astra Nullus is part of Brown's Frontier Saga, which already boasts scores of books about the adventures of Nathan Scott and his crewmates from the Aurora. Haddix isn't Brown. Not even close. He's got a distinct style. In Deeper, Jax almost immediately discovers that his day won't be good. He's facing an extinction event, as some ancient evil has been excavated without his knowledge from the many miles of mines beneath the corporate owned planet. Haddix is a good writer. In fact, the action in his debut Frontiers Saga novel doesn't let up. His characters must adapt to survive. At one point one tells the other, "This is the part in the horror flick where people start dying." Another character responds, "They already have." The book ends with a cliffhanger, so expect a followup.
