Generation Loss by Elizabeth Hand

Cass Neary is not afraid of living on the edge. A photographer whose shots of New York's punk scene in the seventies briefly earned her fame, cache, and a cultish kind of cool, Cass has spent much of her life since then in the dark, watching and waiting. But thirty years later she is alone, adrift, and falling rapidly into oblivion.

So when an old acquaintance asks her to interview a fellow photographer - a notorious recluse who lives on an island off the coast of Maine - she accepts. There, she stumbles across a decades-old crime still claiming new victims. Amid this inhospitable hinterland, Cass comes to realise that her final shot might also be her shot at redemption.
