Kids’ Ketch, 132 Second St., Lewes, will host a mermaid event from 10:30 a.m. to 12:30 p.m. Aug. 3 to celebrate “The Mermaid in Rehoboth Bay,” a children’s picture book published by Cat & Mouse Press.

Children will meet and take pictures with a mermaid, and children who attend will receive a free mermaid sticker. Nancy Sakaduski, author of “The Mermaid in Rehoboth Bay,” will inscribe and sign each book purchased. Children are welcome to come in costume — as mermaids or other sea creatures — if they wish.

For information, call 645-8448.
