The Name of the Star by Maureen Johnson

"The day Louisiana teenager Rory Deveaux arrives in London marks a memorable occasion. For Rory, it's the start of a new life at a London boarding school. But for many, this will be remembered as the day a series of brutal murders broke out across the city, gruesome crimes mimicking the horrific Jack the Ripper events of more than a century ago.

Soon “Rippermania” takes hold of modern-day London, and the police are left with few leads and no witnesses. Except one. Rory spotted the man police believe to be the prime suspect. But she is the only one who saw him. Even her roommate, who was walking with her at the time, didn't notice the mysterious man. So why can only Rory see him? And more urgently, why has Rory become his next target? In this edge-of-your-seat thriller, full of suspense, humor, and romance, Rory will learn the truth about the secret ghost police of London and discover her own shocking abilities."

Me gusta this book. It's very different from anything I've read before, in a really good way. I liked the history integration, I learned some new things. It was a creepy book, which I  kinda have a thing for, and as ghost/mystery stories go, this one was original and well-written and captivating. The characters were pretty varied and not really stereotypical, and surprised me a couple times. Some bits were a bit predictable, but with a description like that it's bound to happen. Honestly, it was new and caught my attention and built intensity until the end and got me attached to the characters and you should read it if you're into creepy/ghost stories. Go. Do it. It's at Kettleson.
