Internal Combustion collects the “illustrated tantrums” of Ashley Holt, as featured on his online Substack journal The Symptoms. Chronicling the misspent life and anguished observations of this award-winning malcontent, Ashley’s essays address both universal truths and the pressing issues of our day: lethargic physicians, obsolescent electronics, Southern accents, and the perils of LSD. What’s more, Internal Combustion can serve as a self-help test for the inquisitive reader. If you find yourself able to relate to Holt’s neurotic commentary and general agitated state, you are a likely candidate for extensive therapy and psychotropic prescription. Or, like most people who encounter his work, you may choose to simply laugh at his pain. It’s a heartfelt journey through one man’s lifelong emotional turmoil. With cute drawings.
