In the not-too-distant future, remnants of humanity shelter in Locryn Castle trying desperately to survive the endless night. Little do they know, everything they’ve built is about to be threatened by forces against which they are unmatched.

Castle security questions the new visitors and Darcy struggles to protect Hope from her sister’s own reckless behavior.

Hope starts a tentative new friendship, and Darcy’s reaction pits them against one another.

Hope’s choices lead her down a dangerous path, and when Darcy tries to help, all their worst nightmares come true.

As Darcy explores her newfound power, she’s filled with equal parts horror, awe and a surprisingly quenchable thirst for vengeance.

Beset by guilt, Hope joins Felix and Jepson in the search for Darcy, and none are prepared for what they find.

While Rook helps Darcy navigate her future, she finds herself inexorably pulled to the past.

Hope and Penelope grow closer, but a brutal attack on a nearby village makes it difficult for Hope to advocate for the vampire.

Rook’s loyalties become clear when an ancient villain reveals her bloodthirsty intentions and Darcy’s attempts to stop her go horribly awry.

As the castle is overrun by Kallistrata’s army, everyone is forced to pull together in order to survive. Elsewhere, Jepson is determined to find and eliminate Darcy.

Darcy musters all of her strength to defeat Kallistrata and ensure the safety of those she loves at Castle Locryn.

As the dust settles, Darcy and Hope realize they have one more threat to neutralize, but this time, it’s one of their own.
