An Artificial Life, Kirkus Reviews writes:
In novelist MacArthur’s first-person chronicle of drug dependence, he calls his addiction “Creep” and describes it as a “loping simian” that “lives in a cave at the back of my skull”. MacArthur’s narrative tone is earnest and urgent, rushing past years and events at a steady clip, encompassing both joy and grief. The author’s journey, expressed year by year, is long and grim, but it eventually makes room for the possibility of sunnier skies ahead. Despite its frenetic, unorthodox format, MacArthur’s memoir will appeal, especially to readers who’ve fought addiction themselves. The author’s dialogues with Creep are chilling.
