A dirty, skinny, dog shows up in Sam and Katie's neighborhood. They start to follow it, and they don't like what they see: The Wilson sisters yell at it because it goes in their garden and the Tracy twins chase it on their bikes and throw things at it.

Sam and Katie want the dog to know they'll be its friends. They think it should have a name. Most of all, they want it to like them. But then they do something thoughtless, and after that, it's hard to make things right, especially because the dog now won't come near them.

How they earn the dog's trust, help it find its place in their town and how it gets its name, makes for a heartwarming story told in two voices using prose and poetry. Blue Daisy is illustrated with 20 black-and-white illustrations and includes recipes for dog biscuits and snickerdoodles.
