Chronicle of the Dark Star Series

Liam Saunders-Chang is one of the last humans left on Mars. The son of two scientists who have been racing against time to create technology vital to humanity's survival, Liam, along with his friend Phoebe, will be on the last starliner to depart before Mars, like Earth before it, is destroyed. Or so he thinks. Because before this day is over, Liam and Phoebe will make a series of profound discoveries about the nature of time and space and find out that the human race is just one of many in our universe locked in a dangerous struggle for survival.

Liam and Phoebe, having barely escaped our exploding sun with their lives, are in stasis for the decade-long journey to the rogue planet Delphi, where they hope to meet up with the rest of the human refugees, find help for their injured parents, and pass along the devastating things they discovered on Mars: that someone destroyed their world intentionally, and that that someone might still be after them, trying to finish the job. Phoebe is carrying her own dark secret. One that finds her waking up secretly at various points in their journey, changing their path through space. 

It is Earth year 2256 - but the fate of the few who even remember Earth is perilously in doubt. Mina Saunders-Chang and many of the surviving humans are stranded in the Centauri system, having barely survived their confrontation with the Telphon refugees. Now everyone - human and Telphon alike - is caught in the blast zone of the Centauri supernova. And yet there's only one question Mina is asking: Where are Liam and Phoebe?
