With its volumes on the expiration of a pet, the death of a relative, and divorce, it would be nice if the Life's Challenges series wasn't necessary. But where trauma exists, there will always be picture books up to the challenge of addressing them. This sober explainer tells the story of a little bunny (or possibly a dog) named Sketch, whose life is disrupted when his father is carted away from home one night by the police. Salient details are in place: the cop who gives Sketch a teddy bear, the social worker who answers questions, the children's support group that Sketch joins a few weeks later. Dad's crime goes unspecified, though the six-year sentence suggests something significant. Occasional boxes fill in important facts (what a law is, how it's OK to feel awkward in a jail); and key images--such as speaking to Dad through a fiberglass wall--are not avoided. Higgins' language is well pitched for adults to read to children, while Kirwan's art hits a nice balance between softness and realism.
