This is the second book in the Goodnight series, a family with varied psychic abilities. The focus of the books are on Daisy Goodnight - she speaks to the dead. It sounds cliched, but it's not. This book and the first are fun and slightly unusual in the author's approach to dealing with ghosts.
My favourite parts were when Daisy spoke to her dead relatives - they're always so cheerful and encouraging. Not your usual ghosts. Daisy can also read a part of someones life from an object that was a large part of their life, but it only covers a certain period of time. Like a snapshot of you from 2000, but that snapshot doesn't know what you look like in 2020. It made it very interesting, like a spirit treasure hunt where you collect bits of a dead person until you reach the right piece which knows what you need to know.
In this book Daisy is coerced into hunting for a kidnapped girl. Daddy is a crime lord who won't take no for an answer and the ghosts aren't happy about whatever it is his daughter has gotten involved in, particularly since it's killing them all over again...
