Arena of the Lost Worlds

About

He went into a burning warehouse to rescue a child. The door he kicked open led to another world.
FBI agent and former Marine Mason Marsh is days from retirement when his final mission takes him into a suspected child-trafficking operation in Hawaii. Ordered to retreat as flames consume the building, Mason hears a young boy crying and refuses to leave him behind.
With ten-year-old Graysen in his arms, Mason forces open a hidden door expecting to find an escape route. Instead, they step into a vast alien jungle filled with living traps, deadly creatures, and contestants abducted from worlds across the universe.

They have been chosen for Arena of the Lost Worlds, a brutal survival contest controlled by wealthy alien patrons. Teams of two are hunted, tested, and forced to fight until only one remains. Mason has the weapons and training to keep them alive, but Graysen possesses something even more valuable. He can read the mysterious tablets hidden throughout the arena, and the challenge coin left by his missing father is awakening to a power neither of them understands.

With two feline warriors as uneasy allies, Mason and Graysen begin uncovering the truth behind the contest. Winning will not set them free.

To survive, they may have to destroy the arena itself.

Arena of the Lost Worlds is a military science-fantasy survival adventure about courage, found family, and one man’s promise never to abandon a child.

Arena of the Lost Worlds should appeal to readers who enjoy the deadly survival challenges of The Hunger Games, the mystery and danger of The Maze Runner, and the other-world adventure of Stargate. But instead of teenagers fighting alone, this story pairs a seasoned FBI agent and former Marine with a ten-year-old boy as they are forced through an impossible doorway and into a lethal arena filled with alien creatures and unfamiliar worlds.

Praise for this book

West knows exactly what her readers came for, and she delivers it with real competence. The opening act reads like a tight tactical thriller — Ruth's team banter over fishing-rod receipts, the clipped radio checks, the raid choreography at Lei Hua Motors — and then, with the discovery of the carved door behind the scorched tarp, the book snaps genres without losing its footing. That hinge moment ("Not saltwater. Not diesel. Not Kahului Harbor") is the book's best trick: it earns the portal-fantasy pivot by grounding it in procedural detail first, so the jungle's wrongness actually registers as wrong.

This is exciting book to read, and I would read again
This story immediately grabs your attention with a fantastic premise: an FBI agent preparing to retire, a dangerous child-trafficking investigation, a burning warehouse, and a mysterious doorway leading to another world. Mason Marsh thinks his career is nearly over, but instead he finds himself fighting for survival alongside ten-year-old Graysen Makai in a place that defies everything he knows. What makes the story especially compelling is the contrast between Mason's experience and Graysen's unique abilities. Mason is trained to deal with danger in the real world, while Graysen possesses a mysterious connection to the alien world they have entered. Their circumstances force them to rely on each other, creating a relationship that adds emotional depth to the action and suspense. The alien setting is another major highlight. The combination of a dangerous jungle, lethal creatures, advanced technology, and an ancient leather tablet creates a fascinating blend of science fiction, fantasy, and adventure. The mystery surrounding Graysen's ability to read the tablet adds another layer of intrigue and makes you want to keep turning the pages to discover what its message means. I particularly enjoyed the way the story raises the stakes quickly. What begins as what Mason expects to be his final assignment becomes a fight for survival in an unfamiliar world, with the fate of more than just two people potentially hanging in the balance. Overall, this is an exciting premise for readers who enjoy science fiction, action, mystery, and other-world adventures. The story combines danger, discovery, suspense, and an unlikely partnership between an experienced FBI agent and a remarkable young boy. The mysterious doorway is only the beginning, and the unanswered questions surrounding Graysen and the alien world leave plenty of room for an intriguing adventure.

A Page Turner. What really pulled me in was the relationship between Mason and Graysen. The story could have easily focused only on the action and survival aspect, but having Mason so determined to protect Graysen gave everything that happened a much bigger emotional weight. I especially liked the contrast between Mason’s experience as an agent and soldier and Graysen’s perspective as a ten-year-old suddenly thrown into something completely beyond his understanding.

The arena itself was probably my favorite part. There’s a constant feeling that danger could come from anywhere, and I liked not knowing what kind of creature, challenge, or twist would be waiting for them next. The idea of alien spectators watching the contestants and actually treating their survival like entertainment added another layer to the story that made the situation feel even more unsettling.

The opening pulled me in right away with Mason running into a burning warehouse to save Graysen. I liked the twist of them stepping through a hidden door and ending up in an alien jungle instead of finding an escape route. The survival arena, strange creatures, feline warriors, and mysterious tablets kept things interesting. Mason’s determination to protect Graysen also gave the story a lot of heart.

A Father's Coin, A Son's Fight
West opens her novel with a deceptively quiet hook. FBI agent Mason Marsh sits in his truck in the rain outside a Wailuku office, three weeks from retirement, having already bought a fishing boat and pictured himself with a coffee and a line trailing behind it, no radio demanding a response. It's a grounded, almost mundane opening for a book that within a handful of chapters catapults its protagonist into an alien gladiatorial arena. That contrast is the book's smartest structural choice: by rooting Mason so firmly in an ordinary, tired-cop-wants-to-retire reality first, West makes the science fiction that follows land with real weight instead of reading as generic space opera. Mason's "one last mission" becomes rescuing a ten-year-old boy named Graysen from a burning warehouse, and the pair are transported, via a mysterious hidden door that appears only when every other path is blocked, into an off-world arena where alien patrons force captured contestants to fight for sport, status, and survival.
