The Mad Mick #6

Ultraviolent: Book Six in The Mad Mick Series

Rate this book
Two violent men headed for an inevitable showdown and nothing in their lives will ever be the same again.

This is the crossover book that readers have asked for — the two biggest characters in two powerful series meeting for the first time.

After his last mission collapsed into utter failure, Conor Maguire and his daughter Barb returned to the U.S. only to confirm their worst fears—Conor's friend and longtime handler, Ricardo, is presumed dead. Worse yet, Conor's new boss is none other than the man who ordered the hit, Billy Browning, and he's long held a grudge against Conor. Conor is given an work for Browning or lose his compound to a missile strike.

Seeing no other choice, Conor agrees to Browning's offer, figuring that will give him time to come up with a plan. For months, he carries the satellite phone that Browning gave him, waiting for the inevitable call. When it finally rings, Conor gets his first orders. He's to visit a nearby county and terminate an insurgent named Jim Powell, killing his entire family and his network of supporters.

Conor has killed a lot of men, but he struggles with these orders. He's working for a man he hates at the behest of a cabal of traitors now running the U.S. government. Yet the consequences for failure are the utter destruction of the compound that's kept his friends and family safe since the onset of the collapse. Barb is less uncertain, ready to pull the trigger on this insurgent who means nothing to her. Conor, however, cannot forget the old saying that the enemy of his enemy just might be his friend.

Surprises from beginning to end!

To start off, the author gave a brief synopsis of the past five books to catch you up. I read a book a day. This is so helpful. Thank you.

I am going to miss Conor and Barb's banter. It never stops. It's anything and everything. Oil and water. Love it.
**"What doesn't piss you off, Barb?" She considered. "Tacos. Tacos don't piss me off." "Even if I make them with goat meat?" She curled her lip in disgust. "No, those piss me off. That's taco blasphemy right there."
***"Maybe you ought to send me?" Conor barked out a laugh. "Then he's dead for certain. You're like the bloody lunch lady of death."

Hate to see Mad Mick retire. But I do see Ricardo, Barb and maybe Hugh? Shall we talk about Jim Powell? No. I want to wait and see. Hmmmm...... Every series Horton writes gets better and better. Definitely recommend this book, recommend the whole series. Great read.

This has been the best book in this series so far. The odds went way up and Franklin Horton continues to keep us on our toes by killing off people you could easily have gone into the book thinking was safe. Plus we get that meeting between the Mad Mick and Jim Powell from the borrowed world series. I was on the edge of my seat from the start through the finish.

I only came for the crossover.

There I was contentedly diving into book #9 of The Borrowed World series, only to discover that the typical prologue had some rather unfamiliar new information that I didn't remember reading about. After getting promptly disgruntled about being mildly spoiled, I had to go and search where all that unread story was since I DEFINITELY didn't remember reading about it in the previous book. Enter Ultraviolet. After the first book left me a little deflated, I opted not to continue this series. Who would have thought that such a decision would come back to bite me in the butt? I mean, come on Franklin! Would it have been SO difficult for an author's note? Some warning? It woulda been nice to been made aware of the crossover ahead of time before the prologue spoiled me. Oyy.

At any rate, here I am, fully stocked with the information I need for The Borrowed World while feeling only mildly lost for The Mad Mick, (which was to be expected). I know it isn't fair to say this, but I was definitely far more invested in the story once it officially crossed over with Borrowed World. Not that the Mad Mick storyline was a bore, though. It was interesting for what it was, well-written with intriguing characters that I didn't meet in the first book (lovin' me some Ricardo). But the pacing was quite sluggish for the first half of the book due to quite a load of detailed exposition and I didn't get REALLY into it until the latter half (even despite the crossover). And sadly, having met her in the first book, I STILL don't like Barb.

Will I ever come back to finish this series? Unknown. While some of it was certainly appealing, the overall storyline was as meh as I remember it being in the first book. Given the snippets of background I learned within this entry in regard to the previous entries, I STILL don't really much care for where the story came from. Most of me is glad I didn't continue after book #1, though, because the inevitable crossover with Borrowed World would have left me just as disgruntled about spoilers, which this book most DEFINITELY has. At the end of the day, I just wish it was better made known the presence of a crossover within the book itself, just so I didn't have to find out by other means.

Anyways, back to The Borrowed World I go! Click here for my random commentary.

I read the Mad Mick # 1 almost by accident, but I was hooked! It's not my usual genre so I was pleasantly surprised when I finished and couldn't run fast enough to Amazon for the rest of the series.
Mick is what I would call a likable cold blooded killer, but what could you expect from a person who was born and lived the first part of his formative years in Northern Ireland's Belfast and who's father and grandfather spent their lives devoted to making things that go boom to kill the occupying British. By the time he was 10 his father and grandfather were in prison and his mother moved with him to the safety of the US to avoid reprisals in Ireland, moving to Boston however, wasn't much safer and they soon found themselves in West Virginia where his mother would rent out a room to others from Ireland who also wanted anonymity that the Appalachian hills could provide. After Mick does a stint in the military, he marries and then is left to raise his baby girl after his wife is killed by a drunken hit and run driver. He gets revenge by killing the driver with such untraceable precision that he attracts the attention of people who hire assassins to "get the job done" and not have to deal with Federal bureaucracy. Mick has found his niche, the 6 books start with the fall of America. America comes under attack by Mid Easterners planted in this country to cause mass casualty's in major cities and then strike randomly why cities are recovering, of course they have disrupted the power grid so the weak are victimized by the lawless. Mad Mick however is one guy you want on your side when the lights go out, in the first book you understand how "Mad Mick" got his name, his daughter is kidnapped to be put into slavery by a nut job who amassed an army of almost 100 followers. Mick follows in pursuit and almost single handily, those he doesn't kill in pursuit, picking them off one by one he gets at the end on one big wild encounter. The books are very bloody, sometimes humorous,
and never never dull. I couldn't say which was my favorite because I enjoyed everyone of them.
I will be reading more of Franklin Horton.

I finished “Ultraviolent”, book 6 in the Mad Mick series by Franklin Horton (2021). This is a fairly long book in the series, with a lot going on. Connor’s new boss, Browning, tasks Connor with killing Jim Powell, protagonist of the “Borrowed World” series, also by Horton. In fact, this book acts as a bridge between the last Borrowed World book that I read and the next one that I started reading and was instantly confused about, since it started mentioning events that had never taken place in that series. I emailed Horton to ask what was going on and he turned me onto the Mad Mick series. Connor is still angry with and distrustful of Browning and starts looking for ways to get him out of the picture, ideally for good.

This book manages to have a lot of different plot lines running parallel to one another without becoming confusing. There’s plenty of action and the plot gets moved along at a good pace. Horton also leans on the plot device of “no honor among thieves”; bad guys aren’t all united on “team evil”, marching in lockstep towards their common goal. Quite often, a villain is more focused on what benefits them the most as an individual, which results in the baddies fighting each other, leaving others to get caught in the crossfire, at worst. This is a concept that Horton uses effectively, a sort of deus ex machina that doesn’t come across as cheesy or forced.

There are more Mad Mick books, but this is the latest one I have. Going forward, I’m going to alternate between the Mad Mick and Borrowed World series, in case they weave their plots together again. I’ll certainly keep reading Horton’s books.

Look, I’ve been thoroughly entertained. The plot? Zippy. The characters? Love ‘em. I’d follow them into battle, brunch, or a chaotic group text. This series has been a wild ride, full of suspense, drama, and just the right amount of “oh no he didn’t!”

But let’s talk about the real issue here: Conor.

This man has been hyped—HYPED—since book one as a gadget-making genius, a lethal MacGyver with a dark twist. I thought we would be given killer gadgets. Death drones. Poison lip balm. Exploding cufflinks. SOMETHING.

We are now SIX BOOKS DEEP.

Six.

At this point, I’m starting to think Conor’s only real gadget is a business card that says “Professional Gadgeteer (Trust Me, Bro).” If this guy made a paperclip slingshot, I’d throw a party. But alas, Conor’s kill count via gadgets still stands at a solid zero.

I don’t need Bond-level tech, but please, for the love of plot promises, give this man a wrench and a homicidal Roomba or something.

Still, despite this glaring case of gadget deficiency, the story continues to slap. The pacing is tight, the banter is witty, and the characters are charming enough to distract me (temporarily) from GadgetGate 2025.

Here’s hoping book 7 finally delivers on the murder gizmos. Otherwise, I’m starting a support group.

In the aftermath of the disastrous mission in book 5 and the disappearance and suspected death of Conor's boss Ricardo, this book gives us the story of Ricardo, Conor, and the scumbag Billy Browning. It turns out that Ricardo was not killed and is on the run. The story of Ricardo was actually the best part. Since everyone thinks he is already dead, Ricardo lays low with the help of some trusted allies. Meanwhile, Billy Browning, the shady ex-CIA guy and Mad Mick nemesis, is now calling the shots. Browning sends Conor on a mission to kill civilians under threat of destruction of Conor's compound. Naturally, Conor outmaneuver's Browning and makes allies with the target instead. Ricardo makes his way to Conor's compound at about the same time Conor and Browning arrive. The grand showdown results in Ricardo rebranding his business, Browning dead and disgraced, and Conor slipping into retirement.

Not my favorite MM book, but a fitting end to the series.

Ultraviolet. Franklin Horton

As usual another action packed thriller which I have become accustomed to every time I read a Franklin Horton book. An enemy from Conor's past has resurfaced. Everyone associated with his handler and good friend has been murdered. Anyone deemed a threat who doesn't concede to the current power's to be is targeted for termination. All weapons are to be turned in or confiscated. Then the general population will be moved into secure settlements where all needs will be provided for. Failure to comply? Death. Obviously Conor his daughter and friends will make a stand. Another excellent read in this series!!! Enjoyed immensely!!!

A wonderful crossover story featuring two of our favorite Horton characters! Interestingly, the first third of the book concentrates on someone else, and I didn't mind a bit. I was drawn in to this thread, trusting that it would all be neatly tied together at some point. I wasn't disappointed.

The different characters and subplots all come together in a masterful crescendo at the end, leaving you reading and flipping pages just as fast as you can.

I keep digging through Amazon hoping to find something from the author that I haven't read yet, but sadly there is nothing else. I've read them all and will just have to wait impatiently for his next book. Get a move on, dammit!

Great Read

I've been reading both The Borrowed World and Mad Mick series sort of in parallel and was glad to see the main characters from both finally meet up. Despite the numerous books in each series this addition kept me hooked from the first page to the last. I rooted for Ricardo, seethed with anger at Browning, laughed at the glimpse of Randi's sass, and worried for that safety of both Connor's and Jim's parties when they finally met face to face. It definitely got a little dicey there for a moment. Now I'm looking forward to diving into the next book in both series. The only question is, which one to read first?

I read this entire series and fully enjoyed most of it. This is a new genre for me, and this is the first I've read that I found engaging, exciting, not poorly written, and not a thinly veiled right-wing, prepper guide. That is, until "Ultraviolent." What a disappointment that the author sank to this predictable trope of 'Murica=Guns! What a shame. Especially since the plot would have easily allowed an alternate approach.

That said, I bit my lip and finished the book. It was a fun ride, but I still felt betrayed.

I just love when the stories from two different series' come together. You always wonder what would happen if two favorite characters happened to cross paths. This is a particularly good case of that. The Mad Mick and Jim Powel finally meet. As expected, it was bound to go poorly before everyone would finally sort it all out. This book also gets a little further into the wider picture of the collapse and the factions vying for power. Looking forward to the next time these two come together.

Series started out 5 star and just keeps getting better!

This book takes on the complex issue of replacing US sovereignty with a one world government overseen by the U.N. inclusive of those champions of human rights - Saudi Arabia and China. First item on the table before it gets into humanitarian aid for the USA is all American citizens must surrender all firearms. That is not a popular discussion for the American citizens or Mad Mick!

I had to stop reading it...

It's a really good book, but life got in the way, and I was distracted for a bit. However when I picked it back up again, the book was easy to jump into, and the characters were like old friends. Barb and Connor are characters that I have come to care about, and Mr. Horton shows that he cares about them too. Oh they get dinged up a bit here, there, but they give back as good as they get!

After the Mad Mick's mission went to pot in the last book, the government threatened to blow up his compound unless he continued to work for them. This did not go over well, as you can imagine. While Connor and Barb start a new mission, we follow Ricardo through his struggle with this governmental faction. The two parties come together for a little bit of revenge.

I like Connor. He cracks me up! I enjoy this sometimes violent, humorous, and informative book series.

Another exciting story from Franklin Horton

I really enjoy Mad Mick and his friends and family. One odd thing in this story was that one of the women was able to maintain her blue hair dye. Didn’t think hair dye was on top of a supply list for surviving an apocalypse. I just have one request from Mr. Horton. Please don’t make us wait so long for the next book.

Another excellent book.

This time around they included a character from the background, I'd say he earned his place well. I think the combining of characters is a well thought out one provoking images of future books. I'll look forward to continuing both series to see how it plays out. Well done my friend, once again you have written an exciting installment of the Mad Mick!

two stories meet

Two of my favorite series meet, both existed in the same world for several books but now cross and the results were great plus the introduction of new characters look to be part of new series which sound as good as the originals if you like apocalyptic fiction you can’t go wrong with any of these bookks

Love the Mad Mick and Mini Mad Mick!

What a great addition to this series. This book had it all, it was a fast action-filled storyline form start to finish. Loved the cross-over story with Jim and crew. I recommend this book and all of the author's other books. So get the books and leave your reviews!

This has been a great series. Loved most of them, and the interaction between Conor and Barb.
For me, the ending of this one seemed a little anti-climatic, though considering everything else that had happened, it guess it was time for something a little easier.
I hope there will be more in the Mad Mick series.

Alliances and Community Rule

This was a wild ride! There is so much happening here that I felt time stand still sometimes as the multi-layered story unfolded. This is top notch writing! I was reminded of my youth when I would read a book a day because they took me to so many places! I highly recommend this one!,

The six book in the saga of Conor Maguire is definitely ultraviolent. Starting off after the failed mission of book 6, "Ultraviolent" does an amazing job of establishing new relationships in the ever present arena of survival in this post-terrorist riddled environment. One of those new relationships is Jim Powell from "The Borrowed World" saga. Ultraviolent is an awesome read.

good storytelling with some misses

Pet peeve: “decimated” literally means “reduced by ten percent.” Several times Ricardo’s group is referred to as having been decimated. If that were true he’d still have 90 percent of them. Yeah that’s picky but details and precision matter to some.

The End??? Are you sure?

This is a great series. Yes, there are a few typos, but the story more than makes up for them. I'd love more Mad Mick books, he's an interesting character with an interesting group of "friends".

Best one yet?

Man this book was a blockbuster. Tons of action, tons of backstory and a little combination of other books mixed in. I can't wait to see where these new alliances go. It's great to see Conor and Jim teaming up.
