Dear Fish by Chris Gall (Little Brown, 2006). When Peter Alan writes inviting the creatures of the sea to visit, they take him up on it. Pufferfish float, a shark bucks a bullrider--talk about a whale of a tale! An imaginative juxtaposition of land and sea. Endpapers include a guide to the featured fishies. Ages 4-up. Highly recommended. Take a PDF peek at the interior pages from Chris' site (bottom right-hand side).
Fanciful book. The appeal reminds me of the "The Lost World: Jurassic Park" where we see the dinosaurs in our world, which was a sort of "King Kong" tribute.
Dear Fish was a 2006 Borders "Original Voices" Book and a Barnes and Noble Book of the Week.
