Her most satisfying book to read out loud is "The Little Island". If you liked "Goodnight Moon" then you'll find this to be an absolute treat. It's also a somewhat odd story, but it's the book that I enjoyed reading to my son the most.

BTW, the book that I disliked reading the most was "The Little Engine That Could". It felt jarring to read -- like I never could quite catch my breath or my rhythm.
