This is a concurrent-measures design because the children are asked to indicate their preference for one book over the other at the same time. There is no manipulation or control of variables over time (longitudinal) or repeated measures of the same subjects (repeated-measures). There is also no pretest or manipulation occurring before the preference task (posttest-only).
