Aliens in garish angelic form chose humankind as one of the races worthy of sharing an otherworldly paradise with them. Most people have already been "decanted." Leo Salmon has not, but he watched as billions around him were transformed into blue gelatinous fluid in preparation for the long trip to Caldo. Leo and the remaining few un-decanted who have been unable to truly receive the "Angel's Promise," a requirement to initiate the transformation, are housed in Walnut Ridge, a pre-decantation facility, awaiting their fates.

The alien ships are leaving in a matter of days. If Leo and the other stragglers are unable to genuinely accept the alien offering in that time, while most of liquified humanity is transported to paradise, Leo and the rest of the abandoned will be left to build a new life on Earth. At least, that's the plan right after they get some Taco Bell.

At face value, Walnut Ridge is an extraordinary account of our inability to transcend the mental trappings of our mortal frailty. However, beneath the stunning imagery and absurd humor of this distinctively unconventional story, you will find a unique allegory for the harrowing trials of mental illness, addiction, and recovery.
