Every day at the sandbar, Finn plays Sharks and Minnows while his brother, Hatch, works in a particular and most-focused way to collect shells. When his ways of collecting may not make sense to his visitors, it is through the advocacy of his brother and the awareness this spreads on the reef that the underwater community understands and celebrates Hatch's marvelous talent.

Finn and Hatch is the first book of The Inclusive Reef Series, where reef animals learn and share about neurodiversity, cognitive ability inclusion, awareness, and advocacy. Hatch shares what it's like to experience reef life as a tang fish with Autism.
