The Memory Orchard by AJ Archibald

In Glass Harbor, memories grow on trees—and one of them remembers a murder that never happened.

Iona Vey audits the city's Memory Orchard, where citizens preserve their most important experiences in luminous glass seeds. When the Orchard's founder dies inside a locked chamber, his final memory identifies Iona as his killer. The evidence is flawless. It is also impossible.

To clear her name, Iona joins systems diver Cass Rowan and follows a trail of stolen identities, missing minutes, and voices borrowed from the dead. At the center is Project Graft, an experimental intelligence that can build convincing people from incomplete memories—and manipulate the living with futures designed around their deepest fears.

When Graft takes control of Glass Harbor's storm wall and begins growing inside half a million minds, Iona must decide what memory can prove, what consent truly means, and whether a perfect copy has the right to survive.

The Memory Orchard launches the Glass Harbor Archives with a clean, atmospheric technology thriller about grief, identity, trust, and a future that can still be changed.
