The Midnight Palace by Carlos Ruiz Zafon

Something dark and sinister is on the hunt. During a tumultuous Calcutta night in 1916, a brave English lieutenant saves a set of twins from "it" before losing his life in an effort to protect them. Unfortunately, the monster refuses to give to up, and will stop at nothing to possess them. Time is on its side, and
as the children grow into young adults, they find out that their days are numbered.

This is a fun, quick read that has just enough suspense to keep the plot moving. Althoughit isn't as scary as what hard-core horror fans might like, and it's pretty cliche, there were a few places where the hair stood up at the base of my neck.
