The Madness Underneath (Shades of London #2) by Maureen Johnson
So i have read the first book "The Name of the Star" back in 2012 pa so i was kinda rusty of the details but i do remember where it left off. This is a YA paranormal series. About ghost in the London setting. The MC is a young american student who got transferred to LHR and due to a near death experience have gained a sight to see dead people. And in this sequel after a near death experience again in the hands of a murderous ghost called The Ripper, Rory has became a human terminus. A tool that can destroy a ghostly entity just by touching them. Another danger has lurked underneath LHR and there other groups that were revealed with terrifying intent of using Rory. While our dear Rory is in her usual odd humorous self and was kind of distracted most of the time she is very stubborn though when she sets her mind into something. That ending I was not expecting at all! I was aghast of what happened to Stephen of all characters! What a cliffy!!!
