Pilot Megan Jacinth has three impossible goals. She has to find her friend Bash, who she left for dead to save her own life. She needs to locate a space-faring entity, using Bash to do so. Then she must unlock this Marauder's ancient secrets. And if she doesn't, millions will die. An alien incursion is coming, and the Marauder's knowledge is the key to survival or annihilation.
When Megan finds Bash, he's being held captive by Gregor Tarrant. Tarrant wants Megan dead - but not before he finds the entity himself, for his own dark goals. Megan is desperate to reach the Marauder first, but the price for unlocking its secrets may be too high. Megan should know, as she still bears the scars from their last encounter . . .
