Jonah Reyes has been dead for four months when his phone starts answering. Dara Whitfield knew it was a bad idea to text her ex's old number at 2 a.m. She didn't expect a reply. She definitely didn't expect a reply that sounded exactly like him. She screenshots it, posts it, and wakes up internet famous for the worst reason available. It isn't a trick. Jonah is a ghost, bound to the building Dara just moved into, still furious about how he died and only slightly less furious about how she left. He can barely lift a glass. He can still ruin her day. And as his unfinished business surfaces-an unpermitted stairwell, an inspector with something to hide-Dara realizes the only witness to his death is a man nobody else can see.
