Eileen Battersby of the Irish Times stated "As one boy’s journey, Lean on Pete is as real as blood: as a novel it is remarkable. Willy Vlautin, romantic and realist, has written something special that will make you shudder, weep, rage and wonder at how such things happen and do, and how some individuals such as Charley can suffer them, absorb the grief, and somehow survive. How good is contemporary US fiction? This good: catch your breath good.” Cheryl Strayed of The Oregonian states "By the time ‘Lean on Pete’ reaches its sweet but unsentimental end, Charley Thompson isn't a character in a novel, but a boy readers have come to love.
