What happened that day would shatter the Miller family. Chloe couldn't be saved, but her parents soon discover the unthinkable: her death may not have been natural. And if the killer hiding among the nurses isn't found more children will die. Healing from the events comes at a devastating cost. For Winslow, that journey begins with a letter-a letter that starts with "Dear Chloe" and unravels the dark secret of April 18th¿and The Night Nurse.
