A castle. A curse. One dangerous holiday.

Leo has invited Kate and a few friends to spend the summer at his
inheritance, Darkmere Castle: as wild and remote as it is beautiful.
Kate thinks it will be the perfect place for her and Leo to
get together – but instead, she’s drawn into the dark story of a
young nineteenth-century bride who haunts the tunnels and towers
of the house … and whose curse now hangs over them all.
