MERLIN RAJ AND THE SANTA ALGORITHM

In this middle-grade novel, a service dog and his human learn about algorithms in daily life.

Author Priya (who writes for adults as Priya Ardis) introduces readers to Merlin Raj, a sock-loving golden retriever who goes to class with his 10-year-old owner, Matthew, who misses “Mom Raj,” who’s traveling for work. Miss Babbage teaches Matthew’s class about algorithms and assigns the kids to create their own, and Merlin eagerly joins in—devising algorithms for everything from locating a missing recipe to keeping the local bully from snagging the best Christmas tree. Matthew uses the Christmas tree experience for his algorithm assignment, and Merlin realizes that what the boy wants most is to have his mother home for Christmas. So the dog implements a series of his own algorithms to make it happen, leading to a happy holiday for everyone. The book presents a lighthearted approach to introductory STEM lessons, explaining the fundamental concept of an algorithm outside the context of computer programming. However, the examples presented seem insufficiently granular to present the concept effectively. For instance, Merlin’s algorithm for getting Matthew a forbidden box of sugary cereal at the grocery store involves hiding the box in the cart and making puppy-dog eyes at the checkout. However, the more conceptual discussion of algorithms is well done, and the story is satisfying and emotionally resonant overall. Merlin’s narrative voice is child-friendly and distinctive (“Research sounded like a pile of socks fresh out of the laundry,” he notes approvingly at one point). Merlin is described as being a service animal for Matthew, who has some difficulties with walking, and the dog’s description of his role (“I’d been taking care of my best friend for a whole year now”) includes enough detail to make it easy to picture the two making their way through school. A glossary defines scientific terms in the narrative, and Miss Babbage’s pronouncements on algorithms are in bold text, making them stand out. Hampe’s black-and-white illustrations add depth to the story, giving readers another window into Merlin’s determination and creativity.

A basic but enjoyable STEM-centered novel for young readers.
