Molly Fyde and the Blood of Billions (The Bern Saga #3)
It's been ten years since Molly last set foot on her birth planet, and this isn't how she'd imagined her homecoming. The sky is full of an invading fleet, one powerful enough to threaten the entire galaxy. The new family she has come to rely on -- her crew of alien misfits and runaways -- are scattered in three directions. As they struggle to reunite, events beyond their control seem to be driving more than just them apart: the universe itself may be torn asunder if the bond between these unlikely heroes is broken.
