Schools are out. Neural maps are in. Learning is instant.

Neural maps embed skills and knowledge directly into the brain, and Yara Relyk was given all that her family could afford. She’s been working at a Synapse mapping centre for five years and has finally scraped together enough maps for a promotion, but there’s one problem. Landon, the coworker who arrived just six months ago, already has enough maps to compete for the same position.

Jay Relyk was given nothing. Labelled mapless and written off as a failure by even his sister, he secretly navigates the dangerous world of illegal maps. Working as a ghost courier, his anonymity is his greatest weapon. But with the new government-sponsored mapping initiative drying up jobs, he is forced to take greater risks.

Both siblings struggle in their own way to survive and care for their mother, whose mind is slipping away one memory at a time.

But when Yara begins to discover cracks in the system she has built her future around, and Jay is drawn deeper into the underground, the lives they have fought to keep separate begin to converge.

When their worlds finally collide, will the truth bring them together or tear them apart?
