Sentinels of the Galaxy Series by Maria V. Snyder

“The answer is no, Lyra,” my mother utters her favorite—I swear—phrase. No means I have to travel with them to another planet—again. No means leaving all my friends fifty years in the past. Thanks, Einstein. Seventeen-year-old Lyra Daniels can’t truly blame Einstein or her parents for their impending move across the Milky Way Galaxy. It’s all due to the invention of the Q-net, which made traveling the vast distances in space possible—with one big caveat: the time dilation... more“The answer is no, Lyra,” my mother utters her favorite—I swear—phrase. No means I have to travel with them to another planet—again. No means leaving all my friends fifty years in the past. Thanks, Einstein. Seventeen-year-old Lyra Daniels can’t truly blame Einstein or her parents for their impending move across the Milky Way Galaxy. It’s all due to the invention of the Q-net, which made traveling the vast distances in space possible—with one big caveat: the time dilation. But that never stopped Lyra's ancestors from exploring the Milky Way, searching for resources and exoplanets to colonize. What they didn’t expect to find is life-sized terracotta Warriors buried on twenty-one different exoplanets. ... Make that twenty-two. As the Galaxy’s leading experts on the Warriors, Lyra's parents are thrilled by the new discovery, sending them—and her—fifty years into the future. Her social life in ruins, she fills her lonely days by illegally worming into the Q-net. The only person close to her age is the annoyingly irresistible security officer who threatens to throw her into the brig. After the planet they just left goes silent—meaning no communications from them at all—security has bigger problems to deal with than Lyra, especially when vital data files go missing. But that's just the beginning, because they’re not as alone as they thought on their new planet... and suddenly time isn't the only thing working against them. less

Year 2522. Lyra Daniels is dead.Okay, so I only died for sixty-six seconds. But when I came back to life, I got a brand new name and a snazzy new uniform. Go me! Seriously, though, it's very important that Lyra Daniels stays dead, at least as far as my ex-friend Jarren, the murdering looter, knows.While dying is the scariest thing that's happened to me, it morphed my worming skills. I can manipulate the Q-net like never before... moreYear 2522. Lyra Daniels is dead.Okay, so I only died for sixty-six seconds. But when I came back to life, I got a brand new name and a snazzy new uniform. Go me! Seriously, though, it's very important that Lyra Daniels stays dead, at least as far as my ex-friend Jarren, the murdering looter, knows.While dying is the scariest thing that's happened to me, it morphed my worming skills. I can manipulate the Q-net like never before. But Jarren has blocked us from communicating with the rest of the galaxy and now they believe we've gone silent, like Planet Xinji (where silent really means dead).A Protector Class spaceship is coming to our rescue, but we still have to survive almost two years before they arrive - if they arrive at all. Until then, we have to figure out how to stop an unstoppable alien threat. And it's only a matter of time before Jarren learns I'm not dead and returns to finish what he started.There's no way I'm going to let Jarren win. Instead I'll do whatever it takes to save the people I love. But even I'm running out of ideas... less

Year 2522. Oh. My. Stars.Junior Officer Ara Lawrence here, reporting for duty. Again. It's situation critical for the security team and everyone in the base - including my parents - with a new attack from the looters imminent, a possible galaxy-wide crime conspiracy and an unstoppable alien threat. But this all pales in the face of my mind-blowing discovery about the Q-net. Of course, no one believes me. I'm not sure I believe me. It could just be a stress-induced delusion... moreYear 2522. Oh.

But this all pales in the face of my mind-blowing discovery about the Q-net. Of course, no one believes me. I'm not sure I believe me. It could just be a stress-induced delusion. That's what my parents seem to believe...Their concern for me is hampering my ability to do my job. I know they love me, but with the Q-net in my corner, I'm the only one who can help the security team beat the shadowy aliens from the pits we discovered. We're holding them at bay, for now, but the entire Milky Way Galaxy is in danger of being overrun.With battles on too many fronts, it's looking dire. But one thing I've learned is when people I love are in jeopardy, I'll never give up trying to save them. Not until my dying breath. Which could very well be today... less
