In the second book in Ruby Jean Cottle's dark and romantic Black River duology, a group of teens must face new supernatural threats while guarding the secrets that could tear them apart.

When Dusty Silver changed over the summer, her sister Opi never expected to share the same inexplicable fate. Now, Opi is burdened with an insatiable thirst for blood and a shame she can’t outrun.

Haunted by visions of Opi in danger, Dusty enlists Eli to watch over her. With him, Opi can let her walls down, but she's caught between who she was and who she’s becoming. And the line between love and bloodlust is blurring fast.

When a body is discovered in the woods, an unrelenting detective starts digging into the town’s trail of unsolved deaths, threatening to expose everything the Silver sisters and their friends have hidden. If Opi wants to protect the people she loves, she may have to embrace the darkness she’s been fighting.

As new romances bloom and loyalties are tested, the group is forced to face impossible questions about themselves and their relationships.

Whatever is hiding in the mountain isn’t finished with them. The worst may still be to come.
