Unleashing Mayhem (Demon Bound Book 4) by Grae Bryan

His friend has his own demon protector so maybe summoning his own will be just what Matteo needs to overcome his fears. Nightmare has been waiting for Matteo, he will protect him at all cost, and then bond to keep him forever. 


From the Unleashing Mayhem blurb:

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.


SNik's review:

Fourth and finale in series (Demon Bound), best if read in order. Paranormal. Found family. Dual POV. Heed content warnings. 

Terrorized for most of his life, Matteo has been hiding with a new friend, and soon realizes he needs a protector he can call his own to help overcome his constant fear. Nightmare has been waiting patiently for Matteo to summon him, there is no doubt that he will willingly be Matteo’s weapon in revenge while waiting to bond with his sweet human mate. 

Wouldn’t everyone like a powerful partner that would do anything for you? I really appreciated that not only is Matteo not afraid of Nightmare, he embraces him, and becomes a little braver from Nightmare’s presence as well as basking in his unwavering affection and commitment. There is no doubt that these two have a special connection, Nightmare gains someone he can care for and accepts his violence, and they are super steamy together. A violent cinnamon roll demon claims his resilient mate, and they get their HEA with their family of demons and humans. Loved this series.

Jacqueleen the Reading Queen's review:

"𝚈𝚘𝚞 𝚕𝚎𝚝 𝚊 𝚖𝚘𝚗𝚜𝚝𝚎𝚛 𝚒𝚗 𝚝𝚑𝚊𝚝 𝚗𝚒𝚐𝚑𝚝, 𝙼𝚊𝚝𝚝𝚎𝚘. 𝙰𝚗𝚍 𝙸 𝚊𝚖 𝚗𝚎𝚟𝚎𝚛, 𝚎𝚟𝚎𝚛 𝚕𝚎𝚊𝚟𝚒𝚗𝚐."

I've been waiting for Nightmare and Matty's story ever since I realized they were going to end up together. I mean, what an odd pairing. Matty is scared of everything, understandably after what he went through in the past, while Nightmare is, well, a Nightmare demon. He haunts dreams and feeds on fear. I could see why he would have an interest in a scared human. It would be like a daily buffet, but I didn't know how Matty was going to feel about it all.

Thankfully I needn't have worried. Matty has layers. He may come off as a timid man, but inside he's hiding a fire that Nightmare has no problem coaxing out. Demons have never hurt Matty like humans have. All they have ever done is protect him, and so he trusts Nightmare to do the same. I don't think Matty expected a mating was going to be the climax of him summoning said demon, but he certainly isn't unhappy it worked out that way.

I loved seeing how Nightmare was with Matty. It was completely different from how he treated anyone else. He was so protective and caring. He made Matty feel safe for the first time in a long time. It was also funny to see how weary all the other demons were around him, even when Matty was present. Kai even tried protecting Matty at first, which was sweet. Funnily enough, Matty was the one to put Kai in his place when it came to his bond with Nightmare. Matty may have had a problem sticking up for himself in the past, but he had no issue telling anyone off who spoke badly of his demon.

I have loved every book in this series and am bummed it has come to an end. I am looking forward to see where Bryan takes us next with their writing. And though I'll miss these demons and their mates, history has shown me that Bryan will soon give us another bunch of paranormals to fall in love with soon.
