Chicago detective Lauren Medina’s latest call brings her to investigate a brutally murdered teenager in Humboldt Park—a crime eerily similar to the murder of her sister decades before. Unlike her straight-laced partner, she recognizes the crime, and the new graffiti popping up all over the city, for what it really means: the Pied Piper has returned.
When more children are found dead, Lauren is certain her suspicion is correct. Still reeling from the recent death of her father, she knows she must find out who has summoned him again, and why, before more people die. Lauren’s torn between protecting the city she has sworn to keep safe, and keeping a promise she made long ago with her sister’s murderer. She may have to ruin her life by exposing her secrets and lies to stop the Pied Piper before he collects.
