Purple, green and yellow
Picture book · ages 3–7 · 380L · 1992
Pure chaos and slapstick that kids find hilarious and parents find themselves rereading; the marker-on-everything premise never gets old.

Love You Forever
Picture book · ages 4–8 · 2019
The most emotionally honest parent-child book in print; the ending breaks adults and reassures kids that love persists beyond death and role-reversal.
