Lockwood & Co. The screaming Staircase is the first book in the Lockwood & Co. series, and I think you will enjoy it.
In this book, ghosts have taken over London. Lockwood & Co. is an agency that helps destroy these ghosts and make London safer for its citizens. The agency contains three agents: Lucy Carlyle, Anthony Lockwood, and George Cubbins. Lockwood and Lucy accidentally set fire to a house on one of their missions and must solve the mystery of the most haunted house in London to pay their debt.
I really like this book, because there is a lot of suspense, and a lot of comedy as well. The story is told in Lucy's perspective, so you really get to discover her inner emotions, and I enjoy that. Lockwood keeps his emotions hidden, but the story really progresses as you discover his backstory. And George is an
amazing comic relief.
Overall, I recommend this book! I hope you like it.
