24/7 Demon Mart #1

The Graveyard Shift

Rate this book
A frightfully funny novel for fans of Tom Holt and Christopher Moore.

Lloyd Wallace is the most clueless crossing guard the intersection of hell and earth has ever seen. So clueless, that he doesn't even realize the beer cave in the corner store where he works is the gateway to hell.

The gate needs a hero, but Lloyd's a zero, a loser with a capital L. He's ten thousand dollars in debt and lives with his parents. He's been fired from every job he's ever had. He was the first thing his ex-girlfriend tossed to the curb when she upgraded her life.

He had no money and no prospects until the night he accidentally slayed a one-eyed tentacle monster hellbent on world domination. And, impressed by his pure heart and bravery, the suave but devilish owner of the 24/7 Dairy Mart gave Lloyd a job.

His coworkers—a karate-chopping bombshell and a talking roach with a really bad attitude—need Lloyd's help to keep the demons in line. Can he man up and become a world-saving hero? Or, will he remain a couch-surfing zero? The fate of the world is on the line. What could go wrong?

THE GRAVEYARD SHIFT had a lot of heart and good intentions but it failed in execution. This is the type of story that's right up my alley, a fun monster romp that doesn't take itself too seriously. Unfortunately, I found the narrative clunky and over-repetitive. If this went through a solid editing process, it could sparkle. Instead, it falls flat for me.

The premise is very good. An unsuspecting, directionless kid takes on a job at a convivence store. Thinking its just another throwaway job to keep his mom happy and bills paid, he finds the job pays ridiculously well and is chock full of corporate level perks. Of course, he's unaware of the hazards he must face every shift. Turns out, the 24/7 Demon Mart is a gate to Hell after mindnight. And the demons stop in for more than just a pack of smokes and a Red Bull.

The book is loaded with fun characters. The manager is a talking cockroach. One of the regulars is a giant centipede and the doughnuts in the doughnut case are not to be eaten at any cost. There's even a magic 8-ball that doubles as a guardian angel.

Everything, on paper, should make this a home run read for me. But, its the writing. Barely passable. I wanted to quit the book many, many times. But I fought through. There's a ton of potential for a great book here but it needs a lot of cleaning up.

There are more books in the 24/7 Demon Mart series. I just don't see myself following through on the rest based on the rough writing in this one. I hope D.M. Guay has gotten better with time or at least get's someone to give her an honest edit. Her storytelling has got tons of potential with improvement.

So I got a Kindle, now I'm reading crazy.
3rd review in one day.

This is pure unadulterated humor horror, or if you prefer, horror humor.

21 year old Lloyd, basement dweller, the kind of basement where the parents live upstairs and Mom does your laundry and makes you a homemade dinner each and every, gamer, slacker, loser, slob stumbles into a job at the local convenience store by day, demon mart by night.

It doesn't take long for the f-bombs to be flying along with some Cheetos mosquitoes, a wrestling loving gentle blob monster whose hero happens to be The Rock, a swanky succubus and many more anomalies that may/may not have the proper paperwork to exit the hell portal located in the beer cave for a night on the town. Lloyd's freaking out.
Did I mention his co-workers, the cool ass kicking chick and the talking cockroach Kevin who's heavy into Dio?
How about his boss, a suave snappy dressed demon who knows the soul of those, but pays well? The many awesome perks of the job?

This is what I put up with. Silly foolishness. Monsters galore. Otherworldly shenanigans and peculiarities. Lloyd has yet to read the work manual, and for all that is sacred, don't eat the damn donuts. I don't even want to know about the cleaners.
Poor Lloyd. Reluctant cowardly antihero.

All out creature feature mixed with odd blood, odd guts, hell spiders, end of world scenarios, a dooms day leader who oops, get it wrong, slushies to the hearts content, OTT non stop funny business, and that humor I tend to lean to. It's all here and I was in my happy place from start to finish.

Theres a slew in this series. I know where to go when I crave a donut.

This book had zero right being as good as it was. It felt like Kevin Smith decided to fuse Clerks and Dogma Dragonball Z style. The characters were beautifully fleshed out and I felt genuinely concerned for their well-being amidst the numerous hellgate fiascos they faced.

I dunno how to start this one. I laughed my butt off for most of this, but the main MC, Lloyd is really unlikable. I mean, he is a "My Dear" fedora dude in the flesh and I would think he spent a lot of time on certain sections of reddit, because that is how he comes across. He dropped out of college, got kicked out of his girlfriends apartment, and now lives with his parents. He also owes a lot of money to everyone. He has no job, no money, no self respect. Nothing.

One day, he decided to go get a slushie with the remaining money he had only to find out that he must have lost some of the coins as he rode his bike to the store. Having already made the slushie, he was thinking of stealing it. Then some weird stuff happens and suddenly he has a job. Now mind you, he never reads the manual for the job so he was thinking that this was a normal store and that is not what he got.

He literally spent the rest of the book learning things he would have already known had he read the book. Or asked questions. Or even used two brain cells.

I have no idea why, but I was sucked into this audio and this new to me narrator, and I am about to start book two.

Main character is a moron.

That sums up how far I got into this book. Having a lazy, forgetful and idiotic main character for a humorous book is funny and, to a certain point, expected. But this guy is too blind, too lazy and too idiotic to bother reading about. I just feel that he is a waste of my time and that ruins what could have been a wonderful reading experience

I wanted to like this. It had everything I normally like in a book, humor, monsters, good concept, but the protagonist’s inner and outer dialogue irritated me. No one is that stupid or clueless. Even with things spelled out he never learned. Really disappointed because was looking forward to reading the series. Unfortunately don’t know if I can attempt the next book.

I saw horror comedy pop on the recs and thought I’d give it a go. Was not disappointed. It was nuts and only got crazier with each new encounter. I’m not sure if I felt sorry for Lloyd or not. He’s slowly becoming a hero and I liked how he takes down nearly every foe with food. Favourite character was Faust and just how easily he gets what he wants. The guardian angel was entertaining and the demon Caroline was just creepy. Curious about Kevin’s roommates. Looking forward to the next one.

1st book in a series that I already know I'm going to love and one that I hope has an extremely long life. It is filled with likeable, almost believable characters who it is very hard not to root for. Hell, I even found myself rooting for the love interests which is something I hardly ever, ever so. I must be getting soft in my old age

In which a hero's journey is more like an ultramarathon... and Lloyd Wallace hates cardio.

This was a delightful read. Quick, imaginative, and funny, with a great cast and a ton of potential for sequels (some of which are already out, waiting for me to read them). I don't think anyone who's ever been to a 24/7 quickmart--especially after dark--would be totally shocked to find it contained a portal to hell, and D.M. leverages that central idea to great effect in introducing not just those tasked with monitoring the portal but also the wide range of creatures who come through it.

The central protagonist, Lloyd, would score somewhere in the negatives on the zero-to-hero scale, but he's helpfully surrounded by a delightful cast of characters who make up for at least some of his many inadequacies. It also helps that his primary concerns (debt, failed romance, and a lack of both direction and motivation) are relatable to a lot of us. By the end of the first book, he hasn't evolved so much as recognized that maybe he needs to, and that sets a great foundation for future books in the series.

Definitely a fun one! I'm excited to see where the story goes.

We didn't finish this book. The main character is so stupid or the author didn't edit enough because the number of times he freaks out or goes over the same details got to the point of exasperation before we'd hit 30% of the book. Also, main character is a self-proclaimed loser and it was hard to listen to all the ways in which he was NOT improving.

Crazy fun story!

A wacky tale of a young man, down on his luck, who discovers his inner hero in the aisles of a convenience store. Odd characters, odder situations. Lovecraft monsters and Bruce Campbell attitude!

Metal!

Fantastic world, crazy fun characters, bonkers monsters, wickedly funny story… This was a hell (ha pun intended) of a good start to what’s likely to be a damned (ha pun intended) enjoyable series. Must-read for fans of horror-comedy.

I have a confession to make. While I read a fair number of books that are supposed to be comedic at least in part, the comedy often escapes me for most of the novel. That wasn’t the case here in The Graveyard Shift. I was laughing very early in the book and sharing the jokes with my son who would laugh uproariously at them second hand. Guay has a gift for the absurd and it really works in this first book of his 24/7 Demon Mart series.

The hero (Lloyd) is a loser. It’s not nice to say, but even he recognizes it. His major problem would appear to be pure laziness coupled with a remarkable lack of even a modicum of ambition. He seems essentially happy living in his parents’ house, playing video games, and going every night to a convenience store to sample one of their 100+ varieties of slushies. Oh, and I should also mention, that he is really, really, stupid. I’m not saying he has a low IQ, just that he’s really amazingly dumb—but weirdly enough, in a totally believable way.

So here’s the set up. Lloyd goes into the convenience store where he has a schoolboy crush on one of the attendants who probably doesn’t know he exists and while he’s there a demonic snake creature appears and tries to escape the store and he helps his fantasy crush stop this from happening. In addition to the snake creature, genuine magic is displayed. Keep this in mind for later.

Long and the short of it is that the store owner arrives and offers our hero a job at an extraordinarily good hourly rate. Since he is in desperate debt, and it will let him be near his crush, our hero accepts. It is very clear to the reader, and in all fairness, the demon hiring Lloyd tells him, that this store is not a normal place. There are genuine threats to life and limb here. There are demons involved. But Lloyd immediately zones out on the training video and never does get around to reading his employee handbook which tells him how to survive these dangers. He also has a really hard time accepting that the supernatural is in play in this store. All of which produces hilarious situation after hilarious situation. It’s as if he just can’t process magic and the supernatural even when he keeps seeing it.

The author also manages to show Lloyd growing as a person without having him overcome the qualities that have made him basically unsuccessful so far in life. So it’s sweet when his mother’s sheer joy that he has gotten a job keeps him from quitting. And it’s also nice to see him starting to want the things that other adults around him desire. Oh, and I should mention that even though Lloyd thinks he is a coward, he’s actually intensely brave and steps up when he has to. And again, credit to the author, this is done in a very believable way.

So, to sum up this review, I really enjoyed this book and am seriously looking forward to reading the rest of the series.

the most questionable 4 i've ever given 🤔

while i was reading this book i'd take pauses just to sht talk the characters sometimes. everything was just so preposterous. my eyes hurt from eye-rolling too much. i guess the premise is so wild, i shoulda seen that coming. basically, 3 characters guard the portal to hell that's disguised as a backroom in a convenience store. Lloyd, the main character is so unlikeable... at first. literally, every time he tells us to "not judge" him for his priorities that were CLEARLY out of whack, i judged him even more. Actually PLENTY characters were quite unlikeable. but somehow... i love this book?

IDK i'm as confused as Lloyd was when he started his job.

WOW!

I LOVED this book! There's a loser dude named Lloyd who can't hold on to a job, a ninja co-worker named DeeDee, and a moody talking cockroach named Kevin... And that's just the employees. What could be better? Oh yea! Throw in some magic, a one-eyed monster, and sketchy (yet delicious looking) doughnuts and you have a fun and interesting first story in the series.

Kevin and DeeDee work at the 24 Hour Demon Mart guarding a gate to where else; HELL. One night in the middle of protecting the humans of the world from a one-eyed monster, in strolls Lloyd... From that moment on hilarity and heroism ensues. With these three guarding the gate, what could possibly go wrong? They might even save the world a time or two... If Lloyd would just read his damn employee manual.

Audiobook review: I stumbled upon this self-published book and I have no regrets, since I’m a big ol’ kid and I love shows like Archer, Futurama (in fact the main character reminded me of Fry) or really anything on Adult Swim. Monsters, demons, talking cockroaches, a motley crew - I’m all in. If you don’t want to read/listen to something with incessant anti-fatness as a device to represent sloth (my opinion of course) or don’t like adult cartoons, especially the crude ones, my guess is you will not enjoy this one. This was excellent as an audiobook and I wonder if that elevated the book for me, regardless I’ll be continuing on and hoping this gets turned into an adult cartoon.

This book wasn't for me. Too much satire, not enough story. It was also incredibly repetitive. I'm sure to others who like this type of book it's great. I'm basically categorizing this as a DNF as I skimmed the last 17%.

This book was so funny! It had a really good base for a whole little series, and Lloyd and DeeDee and Kevin are really good characters. It’s a stupid and funny horror book, and I love that type of genere in horror!! So good

This should definitely be marked as Young Adult, or more correctly, suitable for your annoying 12 year old brother. Fart, butt, puke and boob jokes will be right up his alley, but the sheer number of mentions of “ice Cream Cake” gave this book 1 star, we get it DM, you were stoned whilst writing and really needed some frozen confectionary.

The casually racist “French Exit” ( alluding to the French being rude and leaving without saying goodbye, Google it if you doubt it’s origin) would have taken that 1 star away, if I could rate something as ZERO stars.

It has been (over?) said that men can’t write convincing female characters, this book is proof that this works both ways, female adults can’t write convincing man-baby characters.

I’m so glad that I paid nothing for this trash, it being on the Kindle Unlimited thing…. If you want to read a truly funny, similar genre series, with actual plot and likeable characters, check out Jack Townsends “Tales from the Gas Station” that’s how you write a loser 20something in a dead-end supernatural night shift job

A fun, light-hearted horrorfest

This seriously needs to be picked up as a series on Netflix. Horror comedy on par with Army of Darkness, Shaun of the Dead, etc. Funny, spooky but with a solid heart that will leave you wanting more. Filled with fun characters, and out of this world action that is one part gross, one part cosmic horror, and one part hilarious.

I've been struggling to find something read and honestly I don't know why I bought this. Fate? Who knows, but I read the sample, didn't skip a beat and purchased the book. Halfway through I bought the Chirstmas tale and the sequel. It's that good, you won't regret it. And DM, stick around please, I will need lots of these, so keep writing.

This book is funny as Hell!!!
Right out of the gate this book got me hooked. I like Lloyd's obsession with slushies, video game choices, and his attention to detail like a roach with a name tag reading Kevin. Lloyd is snarky, comical, and awkward. Lloys meets "Mr. Impossibly Handsome" (Asmodius Faust keeper of the gate) afraid he is going down for the great slushie theft. Mr. Impossibly handsome calls him out on all his crap and Lloyd realizes how big of a dumpster fire his life is and gets offered a job.

Welcome Lloyd Lamb Wallace to the 24/7 Demon Mart. You're life is about to get crazy interesting.

I loved everything about this book. The characters are great! The book is insanely funny. The pace is immediately set and consistent. I couldn't put this book down. Enjoy!

What could happen guarding the gates of Hell?

This book is outrageously funny. It will make you smile, snort,roll your eyes and laugh out loud. The story is told in the 1st person,and the great humour is in the main character's (Lloyd) mental dialogue throughout the story. The monsters are extreme in character and description.
The storyline includes the development of Lloyd's meaning in life, beginning of a romance and the fight between good and evil. I'm not going to give a run-down of the story, because the blurb says enough and you really should read it yourself.
Recommended read.

awful. just awful. constantly repeating the same lines, the same information; it felt like reading the same chapter over and over again. and Lloyd is just fucking UNBERAAABLEEE. SOOOOO fucking ANNOYINGGGGGGG 😭

i can’t believe we actually kept reading this. we may as well have just read chapter one and imagined how the rest of it goes and come up with a better story. at least that way we wouldn’t have read the same thing OVER and OVER and OVER interspersed with the worst comedy i’ve read in a book in ages. awful

I've read this book before. I was called Tales from the Gas Station by Jack Townsand. Not to say it is a bad book. If I hadn't read the Tales series, then I may have liked this more. I just felt like I was reading a poorer version.
