Horror and romance aren’t two things that go together very often. At least not the hide-behind-your-pillow-and-hope-the-bad-thing-goes-away kind of horror. But Karina Halle has managed to marry together some genuinely terrifying story lines with an angsty will-they-won’t-they romance in the Experiment in Terror series. It’s birthed something both beautiful and horrifying: the horror romance. A happily ever after where you need to change your knickers for two very different reasons.

Experiment in Terror Series Synopsis
A (very) mature new adult urban fantasy series that is scary, sexy and relatable, filled with the supernatural and things that go bump in the night.
In a large, flaky nutshell, the Experiment in Terror series is an eight-part sci-fi/fantasy/horror series that revolves around a pair of ghost hunters. Well, aspiring ghost hunters, anyway. After filming a creepy experience in her uncle’s dilapidated lighthouse, 22-year old Perry Palomino becomes a YouTube and internet star overnight. She attracts the attention of Dex Foray, a producer and cameraman for a site that specializes in various webisodes, who convinces her to be a host for a low-budget ghost hunting series. The only problem is, neither Perry or Dex are entirely “with it” — I mean, they see ghosts, after all.
And when the duo isn’t wrestling with their very notion of reality, they’re grappling with a working relationship that’s deep-cut with sexual tension. As the series moves on, leading Perry and Dex to new locales and supernatural situations, their lives become more and more intertwined, where they discover that ghosts aren’t the only things that can haunt them.

The Horror
I now consider myself properly seduced by Karina Halle. She did a fantastic job of wrapping horror and romance together in a terrifying and sexy package. Then daring her readers to step into this surreal and scary world. There are some genuinely tense and creepy moments in these books. I know studios have a habit of picking up book series to translate into TV shows, if this happened with EIT I am not sure I would have the wherewithal to watch it. Like I said, I am big ol’ scardy cat.
The Romance
But, lets move on to the romance. The at times:
Wait, did I mention frustrating…romance between Dex and Perry our hero and heroine. This series keeps you on the edge of exasperation and desperation and I know, I know, it sounds awful (and dare I say…frustrating?)! But it isn’t. It’s wonderful. I loved it. I had to keep reading. Sometimes it was because of what was happening in the story line. Sometimes it was because I wanted to get beyond the scary bit. And sometimes it was because I needed to know what the hell the situation was between Dex and Perry.
My Horror Romance Confession
I’ve been reading for a long time. Over that time I have read books from every genre. So, although I experimented in my youth with what all those genres had to offer, I am now well and truly settled into the romance genre. My days of dallying with non-fiction and having hot steamy nights with a saucy little classic number are (more less) over. Horror wasn’t ever a genre I got that into and for one and only one reason. I am a scardy cat.
Then Karina Halle came strolling into my life with her Experiment in Terror series. Bewitching me with her murmurs of a steamy, yet angst ridden romance. With a plus sized heroine. With a dog called Rabbit. A girl only has so much willpower. Plus, the first book was free.
Our thoughts on the Experiment in Terror series
The month of August 2013 will forever remain the month that the Experiment in Terror series by Karina Halle took over our lives’. We couldn’t rest until we had consumed every single book in the series; we were women possessed. The whole month went by with all our texts focussed entirely on the Experiment in Terror series. To give a flavour of the texts in question…
“OMG have you gotten to this part yet…”
“I can’t BELIEVE Dex/Perry did that…”
“Hands off bitch, Dex is mine!”
We couldn’t help it! Karina Halle has done a fantastic job of wrapping horror and romance together in a terrifying and sexy package then throwing it at us for our delight and enjoyment. There are some genuinely scary and creepy moments in these books. In fact, there were points in these books where I had to put them down, take a deep breath, remind myself that ghosts aren’t real, then go back in.
Then there were moments when our hero or heroine, Dex or Perry, had done something that made me wanna sigh like a teenager or throttle them for acting like teenagers. I had to put the book down and take a few moments to calm myself down for that as well! The Experiment in Terror series engages your attention and sucks you in. Even when you are annoyed at the characters, you still have to read on! And I loved it. Dex and Perry are human and make very human mistakes making them feel real and relatable.
The races you’ll find in the series
Every book is so unique. You never know what kind of horrifying mystery Dex and Perry will be looking into next.
There is so much to look forward to in the series. As well more sexual tension than you can shake a stick at, brilliant one liners and emotional moments that rip your tear ducts wide open there are also the monsters. Lots and lots of monsters. Don’t be fooled into thinking that the Experiment in Terror series is fully of the evil-Casper types, although they appear in terrifying and twisted abundance. Karina Halle also explores other monsters that may lurk under our covers (hehe see what I did there?!). So here is a glimpse of the creatures you can expect to pop up in the series ready to scare you into sleeping with the lights on.
