Mel Odom's Master Sergeant is the beginning of a military science fiction trilogy called The Makaum War, and to be fair I have not read book two and three. There is a chance, even if it is merely a fleeting chance, those two books improve on what we have here, but the first entry just doesn't make for a very good read. This isn't because Mel Odom is lacking as a writer, however. The man has been making a living writing books since 1988, and has written for a wide variety of different IPs. Sabrina the Teenage Witch, Buffy the Vampire Slayer, Hellgate: London, Shadowrun, NCIS, Might and Magic, Forgotten Realms, and a few other IPs have all sought his work as an author. As far as I can tell, there is only a small handful of Mel Odom originals, and The Makaum War trilogy are three of those original works.
Here is my plot summary, with spoilers.
Frank Sage has decided to get back into the fight against the Phrenorian Empire, so he requested a transfer from his training position into the front lines. He was instead relocated to Makaum, a "backwater" teeming with rapidly evolving lifeforms and jungle that sits on the edge of a galaxy-spanning conflict. This will be very good for the people stationed there, because Frank Sage is basically perfect in every way.
Although we are promised "brewing civil war with the power to unleash a galactic cataclysm unlike anything ever seen" on the back of the book, the actual actions taken by the military will be against clandestine corporate drug operations. A civil war is mentioned several times in the beginning of the book but is eventually boiled down to mere disagreements between the Quass, or political apparatus, of the native human population. Other than the Phrenorians, several other alien species are mentioned, most notably the ta(Klar). They don't really matter because despite being mentioned several times, they never appear or do anything at all. Earth is referred to as Terra, but despite being about 1000 years in the future, the planet is basically the exact same as it is now.
After being arrested for standing up to the corps on a space station, old grumpy General Whitcomb sends Sage down to the planet with a stern warning. On the planet, he meets up with current Sergeant and man in charge Terracina, who is mere days away from going back home (yes, the days away from retirement trope. He is, of course, doomed). Terracina takes Sage with him on an operation against a drug lab, but it's a trap, and Terracina is killed, along with about a 1/3 of the squad. Sage rallies the troops and eventually manages to route the ambushers, and gets to know Kjersti Kiwanuka, a gifted sniper relegated to Makaum as she rehabs a "cyberarm". Also discovered is evidence of slave labor use by the drug manufacturers and a mass grave of alien slaves infected with a Phrenorian bioweapon; but the consequences of this are then handwaved away by a massive infodump and none of that will come up again.
As Sage navigates all of this, we also get the occasional point of view of Zhoh GhiCemid, a Phrenorian who has fallen from a once high position on the Phrenorian homeworld and is now consigned to Makaum. He is ambushed by one of his underlings and challenged to ritual combat, and Zhoh defeats him and eats his face. Zhoh is stationed at a biolab that is trying to engineer weapons of mass destruction to take over Makaum but settles for making drugs out of toad venom to distribute for money. He does meet Terracina and Sage before the ambush when he and a squad of Phrenorians gun down a group of corp henchmen that the Terrans were trying to arrest.
Sage, after the ambush, identifies the corpses as Dawnstar Corp employees, and goes to confront Velesko Kos, the man he met on the space station when he got arrested during chapter one. This takes place in a nightclub Velesko Kos owns. Sage takes the body of one of the ambushers there and drops it in front of Kos and says he's going to stop all the drug operations in the jungle he's got going on. Several other parties notice Sage's antics in the club; a pair of young natives named Jahup and Noojin, and Zhoh GhiCemid. Kos is about to give the order for his security team to execute sage, but before he can, the Phrenorians step in and demand Sage be allowed to leave alive. This is because Zhoh thinks it will cause chaos amongst the humans on Makaum.
Colonel Halladay, who had been introduced in a debrief after the initial ambush, rescues Sage from Major Finkley, an obviously corrupt jerk who has political connections back on Terra. Finkley was accusing Sage of being a traitor, Halladay knows better than to doubt the amazing Sage. Halladay takes Sage and introduces him to Lieutenant Hadji Murad, a smart young man who is naive and idealistic. Sage then goes to see Kiwanuka, who reveals she is motivated by her brother's death, a medic who was apparently eaten by monkey-like aliens. Sage and Kiwanuka go to a bar to discuss the team's next moves, but are ambushed by Dawnstar mercs instead. They evade the attackers, running through a bustling downtown as their pursuers blow up building and mow down civilians in hunt of their query. Sage and Kiwanuka take out a good number of attackers, and at one point Jahup, the native from the nightclub, bails Sage out with a crucial save. Eventually, air support arrives and the attack is beaten back, but not without severe damage to downtown and an important community gathering place. Phrenorians arrive after the fight and start putting out fires, in an effort to endear themselves to the natives.
After regrouping, the Terran military starts to hit out at targets in the jungle; we get a decent action scene of them clearing out a "biopirate" outpost. Lieutenant Murad reveals his character traits are being overly cautious, and he doesn't want to kill people. They sort of Cape Fear and hold onto the bottom of a big jungle vehicle and hop out once it's in the bad guy strong hold. They defeat the bad guys with some injuries on the good guy side and with Sage engaging in some antics involving blowing up volatile drug chemicals.
We jump forward in time, Sage and his troops have knocked off eight drug labs, and Jahup has become obsessed with Sage. Meanwhile, Colonel Halladay says it's time to go big on a target, because Major Finkley's papa is in bed (politically) with the corps making money from drug manufacturing, and the politics side is pressuring the military brass to cool it. Sage basically says "aight bet" and him and the gang do a daring raid involving flight suits and sleep darts to capture a local Makaum asset who knows about the drug ops.
Noojin is captured and Jahup incapacitated and left for dead by patrolling corps security. As this happens, the Terran military deploys a plan involving infiltrating (with force) the final boss base that involves hacking the mainframe for proof that corps are behind the drugs and deploying two dropships full of troops from the space station once the proof is received. Sage, Kiwanuka, and Murad encounter Jahup in the jungle. Jahup insists he comes along, and they allow it.
Noojin is threatened with sexual violence by Velesko Kos in the base. Sage and his team go into the base while corp security teams engage a fireteam in the jungle. Sage is quick to explode big barrels of chemicals, like this is a video game. Sage almost gets got, but Murad kills his would-be killers. This concludes Murad's character arc. The chemical fire is starting to rage out of control, but Sage manages to get the proof from the mainframe. Jahup goes off to find Noojin and does find her and is saved by Sage from a couple mercenaries.
Sage notices Velesko Kos fleeing and goes after him. He is badly wounded by a mercenary on the way, but eventually manages to take out Kos by mustering up all his strength for one final shot. The dropships were deployed early and have arrived with backup, showing Halladay trusted they would find the proof and pulled the trigger early, thus completing his arc. It is revealed Zhoh GhiCemid was watching all this via satellite. Finally, our book ends on an epilogue, in which Sage awakes in a hospital and discusses a secret Phrenorian base on Makaum with Kiwanuka. Our book ends on a cliffhanger saying the Phrenorian War is coming to Makaum.
The plot itself isn't bad, but the prose is repetitive and dry. Mel Odom writes hungry, and you can tell because we constantly stop the story to eat or drink or talk about what random fruit taste like. There are a few insensitivities sprinkled in, like describing someone's hands working a console moving quickly as "like a spastic" or having Noojin exist solely to be threatened with sexual assault and saved. The sci-fi worldbuilding feels extraneous and tedious to read, and that's tough because it's usually one of my favorite parts of this genre of book.
That said, it is a 2 star rather than 1 star review from me because despite all that, the action sequences were very well done. They were coherent and easy enough to follow, and those parts of the novel became genuine page turners. It's just the rest of it makes it a tough book to not just put down and give up on. At least there were only a few typos that made it through editing.
