Quote from Calistos

(Waving my gumption flag with this one!)

“He’s badly hurt. He needs medical attention.” Marinda tried to push onto her feet but her legs refused to bear her weight and she crashed back onto her knees.

“You are a doctor? A nurse? A practitioner of medicine?” The woman turned hopeful green eyes on her.

They were about to be filled with disappointment instead.

“I’m a cellist.” She braced her hands against her knees and drew down a slow breath to steady her heart. Panicking wasn’t going to get her anywhere. If she wasn’t dreaming, then she had been magically whisked to another place and was at the mercy of her hosts.

If you love Greek gods romance books featuring powerful dark lords of the Underworld and strong heroines who steal their hearts, this paranormal romance series is for you.
Seven powerful Greek god heroes. Seven passionate paranormal romance books. No cliffhangers. Just happily forever afters!
Prince of the Underworld and Lord of Air, Calistos was banished from his home by his father, Hades, two centuries ago and given a new duty and purpose-to keep our world and his from colliding in a calamity foreseen by the Moirai. Together with his six brothers, he fights to defend the gates to the Underworld from daemons bent on breaching them and gaining entrance to that forbidden land, striving to protect his home from their dark influence.
Tormented by the death of his twin sister, Calistos wants nothing more than to find a way to save her soul, but the pain of continuing without her, the constant feeling that he got her killed, is slowly pulling him down into the darkness and he knows it's only a matter of time before he succumbs to the call of the abyss.
Until a battle sets him on a collision course with a kind-hearted and beautiful mortal, one who rouses softer emotions he had sworn he would never risk feeling again, threatening to peel away his mask of playfulness and shatter the barriers around his heart.
Marinda is a woman on a mission-to become a great cellist and repay her father for his faith in her. But her regimented and studious life is thrown into chaos when a handsome man is carted into the ER where she works and takes her hostage, pulling her into a dark and dangerous world... one where she discovers there's more to her than meets the eye and her entire life has been a lie.
When the enemy makes a play for Marinda and the gates, will Calistos find the strength to let someone into his heart again and look to the future, or will the pain of his past lead him to unleash hell on this world?


Calistos is the fifth novel (approx. 425 pages) in Felicity Heaton’s adult paranormal romance series, Guardians Of Hades.

What did I like about Calistos?

I’m already a big Felicity Heaton fan.

I love her writing style and have read most of her books! Her world-building is amazing. The mix of fantasy and reality captures my attention right from the start. I love her characters. They’re never black or white, good or evil but a complex assortment of positive and negative traits and emotions. It’s this combination and attention to detail that always makes her stories feel more realistic for me. 

Calistos exceeding my expectations!

Let me explain. Calistos wasn’t my favourite brother, therefore I came into this book rather reluctantly. However, it soon became clear that I’d made some assumptions about him and his personality that was obviously just for show. I enjoyed seeing a different side of him. Marinda turned out to have all the personality traits that I want from a female protagonist. She’s resilient, intelligent, loyal and strives to fight any injustice. As the quote above proves, she’s also got gumption! Marinda’s a fabulous addition to the female mates!

Now we need to mention the s-e-x. 😉

Felicity writes great sex scenes. They’re explicit but she still makes them feel romantic. This is a talent sadly lacking in many books I’ve read over the years. The erotic scenes are balanced beautifully with poignant internal dialogue and heartfelt revelations from Calistos and Marinda.

Calistos had me hooked and gave me all the feels I crave.

I adored the passionate love scenes. Held my breath during the edge-of-your-seat fight scenes. I was a blubbering mess during the tender and sadder scenes, and I chuckled at the humour and banter. In short, I was gripped from the first page to the last and couldn’t stop reading!

Was there anything I disliked about it?

I absolutely loved everything about this book! (Hence the 5 stars.)

Felicity loves a happy ever after ending for her romantic couples in all her books. So Calistos and Marinda aren’t left hanging, unsatisfied. 😉 The immediate threats are dealt with without the need for a life-or-death cliffhanger either. woohoo! 

However, the story threads that run through the whole series remain unresolved. Felicity tries to ensure that new readers or existing forgetful ones aren’t confused or lost reading Calistos. Vital information from previous books is weaved seamlessly within these pages. However, you’d miss many of the little details jumping straight in or reading these books out of order. For example, you’d miss the nuances of experiencing past relationships, plotlines and knowing the characters – good and evil.

Basically, what I’m saying is…

I really enjoyed this paranormal romance adventure.

I read Greek myths when I was younger and love that they’re the inspiration for this series. With Felicity’s usual twist, of course

Calistos was a great read, engaging me from the very first page! It made me smile, cry and feel all hot and bothered (in a good way). I loved the well-written erotic thrills, kick-arse fighting, and the romantic gestures sprinkled throughout this book.

Content Warning:

There are scenes of explicit sexual content and graphic violence in this book. Therefore, I’d only recommend it to adults who aren’t offended by scenes of this sort.

Who would I recommend Calistos?

Adult readers who enjoy stories with an “acknowledging the darkness but not letting it rule you” element. Those who want characters with hidden depths and stories exploring the lengths we go for family. And of course, readers who, like me, adore tales about soul-saving love with oodles of fire and passion.
