Lennon & Maisy working on picture book

NEW YORK (AP) — Lennon & Maisy, the Canadian-born music and acting team, will soon be Lennon & Maisy the co-authors.

HarperCollins Publishers announced Friday that the young Stella sisters, stars of the TV series "Nashville," are working on the picture book "In the Waves."

Based on their song of the same name, "In the Waves" tells of boogie boards and homemade lemonade and a few unexpected adventures. The illustrations will be by Steve Bjorkman. The book is scheduled to come out April 28.

Hit songs by Lennon & Maisy include "Ho Hey" and "A Life That's Good."
