These alien invaders aren’t what you might expect

If you imagine Martian death-rays or eight-foot-tall bipedal lizards, think again. These alien invaders are called grubs, and for good reason. They travel in enormous packs. They’re “minuscule, maggot-like creatures” capable of aggregating in huge numbers and assuming any desired shape. And they consume just about everything in their path. Including trees and humans—trunks, clothing, and all. They arrived seven years ago in pods that fell all across Earth’s temperate zone. And now, seventy million dead humans later, they occupy most of the continental United States.

Ashley Kelly “was ten when the alien horde arrived.” She and her parents were on their farm in North Carolina when they sighted the first pod reported. Her father lost his life distracting the grubs from his wife and daughter. Now, at seventeen, Ash “has spent seven years learning to walk again” after a cluster bomb meant for the grubs damaged her spine. Confined to a wheelchair, she is evacuated from her last refuge, a Mexico City hospital, and transferred to a massive refugee camp south of the Texas border. She’s been told her long-lost mother is living there.

Then things start to get really interesting.

These are terrestrial grubs. Presumably, they’re different from the grubs in this novel. But who knows? The alien grubs are tiny, and we never get a look at them individually. Image: Farm and Dairy

The humans are losing to the alien invaders

An American officer had lured Ash from the hospital in Mexico City with a promise to reunite her with her long-lost mother. But when she arrives, Ash is horrified to discover that her mother is not among the more than 100,000 Americans sheltered at Camp Augustus. The military is in a desperate, losing battle with the grubs and claims everyone within reach for a role in the war effort. (“Even a cripple like me can work in a munitions factory.”) For Ash, the only saving grace is the attentive young soldier named Jai Davidson who escorts her inside the camp. Jai befriends her, and the two together hold center stage for the duration of the story.

In the face of a surprise attack by the alien invaders on Camp Augustus, Ash and Jai separately make their way northward to the Texas border. There, they team up with the local leader of the American Resistance, a biology professor named McAllister. But it’s wheelchair-bound Ash who holds our attention. And it’s she who breaks through in contact with the aliens.

An ingenious concept of alien life

Welcome to the Occupied States of America involves escalating conflict between the grubs and the American military. Along the way, we witness the appearance of the alien invaders in a startling new configuration. Emerging from beneath the ground in gargantuan numbers, the grubs assemble themselves into “spider-walkers” hundreds of feet high. “They swarm like matryoshka dolls—nested Russian dolls, one inside the other. What we see is billions, probably trillions of seemingly identical cells banding together. Whereas we have specialized cells, it’s as though they’re made from multipurpose cells. It looks as though their cells specialize as limbs, arms, eyes, and tentacles, but they don’t. These are temporary forms. That’s what makes them so damn hard to kill.”

Now, if this description seems beyond belief, the author assures us, in the words of Prof. McAllister, “There are types of amoebae here on Earth that will band together in times of scarcity to form simple creatures capable of motion. Once food becomes abundant again, they’ll dissolve, and return to being individual organisms.”

First Contact—delayed

You might think First Contact took place when Ash and her parents encountered the grubs on their farm in North Carolina. But there was no contact as such, certainly no communication, merely two people fleeing and a third the subject of a feeding frenzy. First Contact—involving a meeting of the minds, as it were—doesn’t happen until nearly halfway through the novel. And of course it’s Ash who is at the center of the action.

I don’t want to spoil the story, but suffice it to say that the ending is a happy one. Or at least as happy as an ending can be. After all, tens of millions die in this gruesome tale. In fact, I found myself disappointed by the way Cawdron winds up the story. It’s an ending only Hollywood could love. Or, perhaps, a fan of YA fiction.
