Hemlock

Mackenzie and Amy were best friends.
Until Amy was brutally murdered.

Since then, Mac's life has been turned upside down. She is being haunted by Amy in her dreams, and an extremist group called the Trackers has come to Mac's hometown of Hemlock to hunt down Amy's killer: A white werewolf.

Lupine syndrome--also known as the werewolf virus--is on the rise across the country. Many of the infected try to hide their symptoms, but bloodlust is not easy to control.

Wanting desperately to put an end to her nightmares, Mac decides to investigate Amy's murder herself. She discovers secrets lurking in the shadows of Hemlock, secrets about Amy's boyfriend, Jason, her good pal Kyle, and especially her late best friend. Mac is thrown into a maelstrom of violence and betrayal that puts her life at risk.
