Unleashing Mayhem

Demon Bound, Book 4

By: Grae Bryan

Narrated by: Michael Ferraiuolo

Matteo’s been running scared for so long he’s forgotten what it’s like to feel safe. Or maybe he never knew in the first place. Raised by a cruel man, tormented by an even crueler one, and recently rescued by a demon, Matty’s still jumping at shadows around every corner. When he sees a familiar face from the past and realizes his ghosts really have come back to haunt him, Matty does the only reasonable thing he can think of.

He summons someone even worse.

Nightmare is a solitary demon by nature. He’s never needed a companion or a lover or a friend, and he’s never minded being feared by others of his kind. But one taste of Matteo’s sweet, terrified soul and Nightmare needs more. When he’s finally summoned to Matteo’s side, Nightmare finds himself exactly where he wants to be. Now it’s only a matter of patience, seduction, and convincing his little human that one contract isn’t enough.

What they really need is an eternity.

Unleashing Mayhem is a heated MM paranormal romance with a HEA and no cliffhanger. It contains a sweet human afraid of everyone but the monster at his side, a demon so possessive even other demons run scared, a found family made of mobsters and monsters, and a summoning gone right (for once). While each book focuses on a different couple, the series is best enjoyed in order.

Love the Mayham

A fun twist on Nightmares and those who live with them-yeah, that was intentional. Not my favorite Chaos demon, but Nightmare is a second favorite.

Perfect ending

I have been waiting for this story since book 1, and it didn’t disappoint. Absolutely loved it!

Relationship Goals😍😍😍😍😍

I love how sweet nightmare and Matteo’s relationship they are tied for my favorites with chaos and cooper and Sascha and Kai Ivan and nix are cute but way less of relationship goals as the others

My favorite book in the series!!

Well this is hands down my favorite book in the series. I just adored Matty and his Nightmare. I'd say that this might be the darkest book of the series as well, but there is such a softness and sweetness to Matty as he heals from his past and finds love with the scariest demon of the bunch, that it never gets *too* dark, if that makes sense.

I loved getting to see so many of the previous couples in this one, and everyone working together to help Matty.

Michael, as always, is an excellent narrator. I loved his voice for Nightmare, I don't think I hear this character voice from him very often if ever.

If you're a fan of hurt/comfort, possessive mates, scary demon/sweet and soft human pairing, and overall demonic shenanigans, then you will love this book. I have really enjoyed the whole series and if this is the last one?? (not sure if it is or not) then it really went out on the highest note for me.

Good series

I like this series. I like that we get to see characters from previous books including the vampire mates series. The narrator gave a good performance.
