Rose Cottage Christmas

It's Christmas at home in Hallowcastle this year, and Kastle, Ciarán and Brigid are hoping it will be a quiet one. Well, to be truthful, Kastle doesn't want things too quiet. His wish is granted when his old friend Aidan Lockwood-Scott visits him during Hallowcastle's Christmas Market.
One of the many members of the Lockwood family, infamous for their psychic powers and the invention of the spirit camera, Aidan has news: his great aunt recently passed away, and she left him her house in Hallowcastle. But there's more. Kastle only met Cassandra Lockwood once, but he is astonished to learn she bequeathed him an antique camera with an unusual past.
There's just one problem. No one has seen the Camera Lucida in forty years.
What secrets hide in 90 Gramercy Park? What has become of the Camera Lucida? Why did Cassandra leave this camera to a near-stranger, rather than one of her numerous - and disgruntled - relatives? Some members of the Lockwood family aren't about to give up on what they think is theirs without a fight, and before long, Kastle finds himself facing a ghost from his past.
