Review first posted at Girl Who Reads. A free copy was provided in exchange for an honest review.As a dreamhacker, Charlie can enter someone else's dream and change its course, though that means she also has narcolepsy. Her skills are in demand, and she uses them for therapeutic reasons to help stop nightmares or anxious dreams. One minor celebrity had dreams of a Creeper before sleepwalking off of a building, however, making Charlie believe she's not the only dreamhacker out there.Charlie describes her skills as a dreamhacker as "Diary of a Call Girl meets Inception," which is rather how it works. She had developed her abilities after participating in a medical trial to address her narcolepsy, and uses them as a therapist. She has to be in the same room as the dreamer, so she often crashes on the floor or an armchair, and afterward leaves to go to another session that is booked for her. There are recordings of the dream sessions where applicable as well as a body cam and an earpiece that works like our smartphones. This version of London 2027 has a lot of wearable devices and programs similar to our own, but just slightly different and a little more advanced. There are programs to have people fall asleep, learn things during that sleep time, and even run simulations and games during that time as well.In between her commentary and excerpts of case files are transcripts of the police interviewing her after Melodie's death. She's a very chatty and irreverent character, so I liked her right away. Other characters in the novel are likable, too; the agents interviewing Charlie have some flashes of personality shining through in the transcripts, and those are entertaining to read. Even before we meet the Creeper in Melodie's dreams, there is an undercurrent of something sinister in BigSky, the massive company that led to testing and is in control of the augmented reality system that people use. The further we go in the novel, there seems to be more and more that the AR touches on, and more of an integrated approach into how it works with the world at large. There is more intrigue and mystery, which entirely sucks me in. I love the mind bending-ness of the story, especially when it gets to the final third of the book. This is a great story, and will leave you with the question about consciousness and reality, and what to do with technology that can alter it.
