Goodreads 201: How Authors Can Get The Most Out Of Goodreads

It was bizarre and inexplicable, but after it happened no one spoke of it and Ingrid Waverly was forced to leave her life in London behind. She had to trade a world full of fancy dresses and society events for Paris with her mother and younger sister, Gabby.
In Paris there are no grand balls or glittering parties, and, disturbingly, the house her twin brother Grayson found for them isn't a house at all. It's an abbey. A creepy, old abbey with a roof lined in stone gargoyles that one could almost mistake for living, breathing creatures.
And Grayson is missing.
Yet no one seems to be concerned about Grayson's whereabouts save for Luc, a devastatingly handsome servant who has some secrets of his own.
There's one secret about the city that he can't keep hidden, though. There's a murderer on the loose. And every day Grayson is missing means that there's less of a chance he's alive.
Ingrid is sure her twin isn't dead—she can feel it deep in her soul—but she knows he's in grave danger, and that it's up to her and Gabby to find him before all hope is lost.
Only the path to him is more than she could ever imagine.
