Marrow Nightingale is a professional pain in the ass. As Electric Blue Moon’s only licensed private investigator, she’s the one who snoops the closets of the elite who think the laws don’t apply to them. But when the son of a wealthy family turns up dead, it’s Marrow’s closet that everyone is suddenly interested in. That dead playboy in the foyer? It’s her adoptive sibling, Rocket Nightingale.

Now, Marrow’s dodging gossip columnists who smell blood in the water, renegade corporate IP with minds of their own, and badge-wearing bone-breakers who would love nothing more than to ship her back to the surface.

Which is still on fire, thank you very much.

If Marrow can’t catch the killer, this case is going to sink the Nightingale Electric Detective Agency.

Welcome to the city under the sea, an old-money refuge for the environmentally ravaged. Where humanity is trying to forget its past with ink-stained cocktails, designer drugs, and genetic modifications. Where Marrow Nightingale may be the last honest scoundrel.
