Edwina Darke is one of a trio of ghost-hunting sisters who rid clients of their unwanted supernatural visitors. A badass by nature, Edwina doesn’t run from haunted houses—she runs into them. Yet no matter how many “ghosts” she debunks, she remains troubled by a demon from her own past. Simon Teal is the co-owner of a historic B&B in Niagara-on-the-Lake, Ontario, a town famous for its connection to the 1812 War. Simon doesn’t believe in the spirit world, but something is chasing his customers away, so he reluctantly allows the Darke sisters to investigate. As the team uncovers the star-crossed love behind the B&B haunting, Edwina and Simon’s attraction flares. It’s the last thing either of them needs. The dedicated Edwina refuses to lose herself in another relationship, and Simon is still reeling from a terrible betrayal. When a darker presence reveals itself, triggering their protective instincts, Edwina and Simon succumb to temptation. But the evil entity has taken an interest in them, and if they don’t solve the mystery, someone new could end up going “into the light.” And it could be one of them.

Historian Susannah Darke is no stranger to haunted houses. As one of a trio of ghost-hunting sisters, she's had plenty of experience investigating the paranormal. When an opportunity arises to explore a haunted opera school in Toronto, she jumps at the chance, even though she once had her own frightening brush with its resident ghosts. Noah Bellamy is the dean of the Asch Institute of Opera, and a former opera singer himself. He was once a student at the Asch and is well-acquainted with its boisterous spirits. But when the activity worsens, threatening one of his star students, he knows he has to take action. The fact that Susannah and Noah have been hooking up for the past year complicates things, but they agreed long ago to keep things casual. As long as they both remember their boundaries, the investigation should go smoothly. When the paranormal activity begins to target them personally, it becomes harder not to seek comfort in each other's arms. For the first time ever, Susannah and Noah have to decide if it's worth taking a chance on love. The ghosts present a huge challenge, but battling their personal demons may be even harder.
