Marvin Monster learns the value of keeping a promise, as he has to deal with a friend's broken commitment and realizes he's guilty of the same.
This is a well-written, readable, accessible story whose underlying lessons about keeping one's commitments are accessible to kids.
Kids under a certain age, maybe 8, won't really grasp the social implications of a "date" and may not have had the same experiences of proto-romantic rejection that Marvin suffers. Thus, the lesson of the book is transmitted, but the message is muted.
He characterized this as a nice story and requested it a couple of times.
Date?! Did someone say "date" around my kids already?! You'll have Simultaneous flash-backs to your own 7th-grade social woes and flash-forwards to where your kid will be in just a few years.
This is a chapter book for early readers
This is a nice read aloud or read-it-yourself story about keeping one's word. Even if your kid doesn't understand a 'date' s/eh can learn about promises.
