The Síle Protocols. The Magician's Granddaughter, #3

Book Three of The Magician's Granddaughter series is set in Perth, Western Australia. Book three is the trilogy closer for the discovery arc established in Books One and Two. Book One established the gift of witnessing, the circle, the Collectors as antagonists, and the first Perth operation. Book Two destroyed the Edinburgh Ledger and corrected the Dublin founding document. Book Three discovers the full shape of the Collector network, destroys the Perth node, and maps the remaining installations.
The Collectors did not just build a network. They encoded it into the earth- ley lines repurposed, locked, and laid into the foundations of buildings across the Earth. The Perth node has been running for a hundred and thirty years. The building above it is scheduled for demolition in eleven days. Immie has to read the map of everything the Collectors have been hiding before they demolish the evidence.
The operation is not a break-in. It is a reading.
