This spring’s crop of picture books for children focuses on friendship, history and nature. With belly laughs!

Go and Get With Rex, by David LaRochelle, illustrated by Mike Wohnoutka. (Candlewick Press, $17.99, due May 7)
A perfect book for kids who know the alphabet but aren’t yet strong readers — or for any kid who likes to laugh. The Theodor Seuss Geisel Award-winning Minnesota duo (whew!) of LaRochelle and Wohnoutka gives us a lesson in things that start with certain letters: F is for frog. M is for moose. But for every letter, Rex the dog fetches a duck. And it turns out that each time, Rex is right! With comical illustrations and a brief, easy-to-read text, this book is both funny and subversively educational.

The Rock in My Throat, by Kao Kalia Yang, illustrated by Jiemei Lin. (Carolrhoda Books, $18.99)
A powerful, melancholy book, with no tidy ending. Born in a refugee camp, young Kalia stops speaking everywhere except at home after her family moves to St. Paul. “I don’t want to be like the many people who speak English,” she says, as she watches how her mother is treated by strangers. She stays silent in school — so silent she cannot make friends. This sensitive book is about a Hmong girl who keeps control the only way she knows how. Yang publishes a second picture book May 28 — “Caged,” illustrated by St. Paul artist Khou Vue. It’s about living in — and leaving — the Thai refugee camp where she was born.

Oskar’s Voyage, by Laura Purdie Salas, illustrated by Kayla Harren. (Minnesota Historical Society Press, $17.95)
Minnesota writer Salas spent a week in 2019 sailing the Great Lakes on a freighter and has turned her experience into a wonderful tale of a stowaway. Oskar the chipmunk follows a crate of tomatoes onto an ore boat and ends up sailing from Duluth to Cleveland and back again. In gentle rhyme, Salas takes us on a tour of the giant boat, from the spotless galley to the pilothouse to the rumbling engine room. Harren’s bright paintings bring the big boat and the wide-open lake to life. An informative, entertaining book for young boat-watchers.

Fresh Juice, by Robert Liu-Trujillo. (Lee & Low, $19.95)
