Description: "An anti-bedtime book about a mermaid who is definitely NOT your typical mermaid!"--
Review Quotes: A 2025 Bank Street College Best Children's Book of the Year
"A fierce young mermaid rebels against prim behavioral advice in Sumner's ornery metafictional title . . . It's a story for the bedtime-avoidant whose curmudgeonly antihero truly shines[.]" --Publishers Weekly "A must for mermaid fans, sweet or sassy, and a great bedtime read." --Kirkus Reviews "This book is utterly original, delightfully dark, and as twisted as a branch of undersea coral. Good night, little mermaid. Sweet nightmares." --Booklist "What is there for the girl unimpressed by the glittering, precious creatures populating many Disney movies and much of kid lit? The one who bristles at tiaras . . . who chafes at any effort toward conformity? [The Good Little Mermaid's Guide to Bedtime] offers a heroine meant just for that girl, a little mermaid with razor-sharp teeth, predatory instincts, and zero interest in being good, sweet, or, most importantly, following [an] evening routine. . . . A contrarian delight." --The Bulletin of the Center for Children's Books
