Summary
"Unscientific garbage." That’s exactly what Tech E. Coyote calls the wildly popular Turbo-Grid Mega-Burgers from The Meteor Grill.
As the brilliant lead scientist of the Loonatics, Tech prides himself on logic, refined nutrition, and total self-control. So, when his hyperactive boyfriend, Rev Runner, gets a sponsorship from the restaurant and begs him to take just one bite, Tech puts on a massive display of absolute disgust, swearing he will never succumb to the greasy street food craze.
But keeping up a stubborn front is hard work, and a single microscopic taste is all it takes to trigger a secret, manic obsession. Driven by a desperate craving he refuses to admit out loud, Tech plots a stealthy 3:00 AM heist to break into Rev's high-security burger vault. Unfortunately for the super-genius, he completely ignores the explicit, hyper-dense caloric warning label on the back of the wrappers.
Now, Tech is about to find out exactly what happens when scientific arrogance meets a ten-burger binge—and just how incredibly soft a 1,500-pound coyote can truly be.
