Will Audrey Rose and Thomas see their last mystery to the end - together and in love - or will their fortunes finally run out when their most depraved adversary makes one final, devastating kill?

Following the grief and horror of her discovery of Jack the Ripper’s true identity, Audrey Rose Wadsworth has no choice but to flee London and its memories. Together with the arrogant yet charming Thomas Cresswell, she journeys to the dark heart of Romania, home to one of Europe’s best schools of forensic medicine… and to another notorious killer, Vlad the Impaler, whose thirst for blood became legend. But her life’s dream is soon tainted by blood-soaked discoveries in the halls of the school’s forbidding castle, and Audrey Rose is compelled to investigate the strangely familiar murders. What she finds brings all her terrifying fears to life once again.

Milly, Aubrey, and Jonah Story are cousins, but they barely know each other, and they’ve never even met their grandmother. Rich and reclusive, she disinherited their parents before they were born. So when they each receive a letter inviting them to work at her island resort for the summer, they’re surprised… and curious.

Their parents are unwavering on one point: not going is not an option. This could be their chance to get back into Grandmother’s good graces. But when the cousins arrive on the island, it’s immediately clear that she has different plans for them. And the longer they stay, the more they realize how mysterious - and dark - their family’s past is.

The entire Story family has secrets. Whatever pulled them apart years ago isn’t over - and this summer, the cousins will learn everything. If they can survive the season.
