"A Lucky Pony," by Mia Coulton. I was familiar with the Danny books published by Mary Ruth Books from my years as a Reading Recovery teacher. My students always enjoyed the books about Danny, and were delighted as the collection grew.
I'll be honest, I'm easily pulled into books by characters. Like my students, I enjoy seeing characters return across multiple titles. Who can resist Ladybug Girl, Bear, Marley, Tacky, or the myriad of other characters who return in picture book after picture book? Thankfully many of the texts designed to support young readers also have characters that return in stories across our collection. My students enjoy Baby Bear, Ben, Mr. Cricket, The Meanies, Tom, Mrs. Wishy-Washy, and many more.
