Thank you to Berkley for inviting me to take part in the blog tour for Enter the Nightmare by Jayne Castle. I’m delighted to share my thoughts on this wonderfully strange, suspenseful, and romantic Harmony novel.
About the Book
Nightmares become real when a woman trying to rebuild her life enters the Hotel of Dreams in this exhilarating Harmony novel by New York Times bestselling author Jayne Castle.
Alice Radstone should have known not to return. Her life before the Hotel of Dreams had been the perfectly cloistered world of a teacher at the Ballantine Academy. When the death of her mentor forced her out, she was left to reinvent herself in the big city. Since then, things have not gone well.
Ten months ago, after her first trip to the hotel, she woke up in the locked ward of a hospital for the criminally insane and was told she had murdered her husband on their wedding night. She has no memory of the husband or the wedding, but after escaping the asylum, one thing is certain: she is never going back.
Unfortunately, Alice’s second reinvented life is also deteriorating rapidly, which is why she finds herself once again at the Hotel of Dreams, this time hiding in the shadows of her room with a dead body in the shower and two men wearing masks creeping toward the bed to kidnap her. Again.
When the enigmatic and decidedly dangerous Owen March shows up and claims he’s there to rescue her, Alice has no choice but to accept his offer and hope that he does not also intend to kidnap her.
With Alice and Owen in the killer’s sights, time is running out. They must trust each other, and the electric passion between them, if they are going to make it out of this hotel alive.
My Review
Harmony is such an interesting place. Every time I pick up one of Jayne Castle’s books set in this world, I’m reminded how much I enjoy her imagination. Creepy alien ruins, psychic abilities, mysterious energy, unusual animal companions, and danger after dark? Yes, please. That is exactly the kind of paranormal chaos I like to wander into from the safety of my couch.
Enter the Nightmare drew me in right away with the Hotel of Dreams, which honestly felt more like the Hotel of Absolutely Not. It has that eerie, unsettling atmosphere where every hallway feels suspicious and every shadow looks like it has bad intentions. The hotel almost became a character itself, and I loved that. It added so much tension and gave the story this dreamy, dangerous quality that worked perfectly with the nightmare elements.
Alice and Owen were also a couple I completely gravitated toward. Alice is trying to rebuild her life after everything has gone sideways in the most dramatic way possible, and Owen has that dangerous, mysterious energy that makes you wonder whether he is the rescue or another problem with excellent timing. Their chemistry was strong, but what I liked even more was how quickly their partnership started to feel solid. Even the marriage-of-convenience element added a fun little spark that made me very happy. I do love a forced alliance with emotional complications. I am only human.
And Sebastian. Sebastian is the absolute best. I want my own Sebastian immediately. No questions. No paperwork. Just hand him over.
The thrills kept the story moving quickly, and I found myself turning pages fast because I needed to know what was going on. There were kidnappers, secrets, psychic weirdness, danger around every corner, and just enough romance to balance the suspense without slowing it down. The characters felt layered and fleshed out, too, which made the danger land harder because I cared about them. I was invested. Possibly too invested. My laundry can confirm.
This is book 18 set in Harmony, but I don’t think readers need to panic about that number. I haven’t read anywhere close to all of them, and I’ve never had trouble jumping in when a new one catches my attention. Each book focuses on different characters, so Harmony itself is the main thread tying everything together.
Enter the Nightmare is inventive, atmospheric, romantic, and wonderfully strange, as Jayne Castle does so well. The paranormal elements were my favorite part, but the suspense, the setting, and Alice and Owen together made this one especially fun.
Floral Verdict: A Rose 🌹
I recommend it, especially if you love paranormal romantic suspense with a vivid world, a dangerous setting, and an animal companion who steals every scene he enters.

Final Thoughts
Enter the Nightmare is exactly the kind of paranormal romantic suspense that makes me happy: imaginative world-building, danger with a pulse, a strong central couple, and the kind of oddball details that make the Harmony books feel distinct. It is eerie, fast-moving, romantic, and just weird enough to keep things sparkling around the edges.
