Mika is not your average twelve-year-old--and she's about to prove it.
It's 1880, and in the frigid city of Stockholm, death lurks around every corner. Twelve-year-old Mika knows that everyone in her orphanage will struggle to survive this winter. But at least the notorious serial killer the Night Raven is finally off the streets...or is he?
Mika is shocked when a newborn baby is left at the orphanage in the middle of the night, by a boy with a cryptic message. Who is he? And who is this "Dark Angel" he speaks of? When a detective shows up, Mika senses something even more sinister is going on.
Drawn in by Mika's unique ability to notice small details--a skill Mika has always used to survive--the gruff Detective Hoff unwittingly recruits her to help him with his investigation into a gruesome murder. Mika knows she should stay far, far away, and yet...with such little hope for her future, could this be an opportunity? Maybe, just maybe, this is Mika's chance to be someone who matters.
