After narrowly escaping marriage to a highborn bigot, he takes an assignment in Brighton, leading him to an abandoned abbey full of dark whispers and a sinister secret society, the very one Henry has been investigating for three years. Isabella is as beautiful as she is talented, but falling in love isn’t part of her plans. She only wants to paint, forget her painful past, and keep her overbearing mother at bay. But gaining one’s independence isn’t easy for a woman in 1823, so she embarks on a fake courtship with Sir Henry. Soon, love and a painting career no longer seem so utterly incompatible. But when the man Isabella fears most kidnaps her, all appears lost. Realizing the kidnapper is part of the same organization he is investigating, Henry chases after them. Entrapped in a web of secrets, both Henry and Isabella must face old enemies and fight for their happily ever after.
