Supernova (The Commons Book 1)

All Lily wants is to start over. A move to the city, with a new job in a cryonics lab is the perfect way to rebuild her life. She just doesn't expect her employers to be a pair of violent, power-hungry aliens with time travel abilities.
Hauling a pile of museum artifacts in a dilapidated patrol ship, the worst things Captain Rian Marska expects to deal with are bickering crew members and a long, lonely trip across the galaxy. An Earth exhibit coming to life and claiming to be from the twenty-first century is the last thing he wants to deal with, as are the feelings she stirs in him.
When Rian's superiors sweep Lily under the rug, they take it upon themselves to find out why she was taken from her own time and what her kidnappers want. What they discover has implications not only for them but for the entire civilized universe.
