The fight for order has only just begun… Fletcher, Ariana and Eli are walkers: carriers of a rare gene that enables them to communicate with animals and bridge our world and the spirit world. It is up to them to avert a catastrophic solar storm that threatens to release a dangerous dark spirit. Yet they’re hunted by a powerful genetics organisation, the MRI, which will stop at nothing to control their powers.
Reeling from loss and betrayal, scientist Robyn Greene must protect the walkers at all costs. Can she figure out the MRI’s plans and help the walkers bring Earth back into balance before it’s too late?
