The good news first: You’ll love this delightful tale. The bad news: Eventually, it comes to an end.

The sweet story — perfect for preschoolers — centers around Rabbit, ever the Pollyanna. Rabbit encourages his pal Mouse, who thinks life’s no picnic, to find the silver lining. But when actual storm clouds roll in and lightning strikes, it’s Mouse who supports his friend.

Jeff Mack’s hilarious picture book may feature just four short words, but it’s extra-long on heart.

Available at amazon.com, $12.
