Hazel and Jack have always been best friends, bonding over their shared love of science fiction and fantasy. They play make-believe “superhero baseball” and hang out in a derelict house they call the Shrieking Shack. But now that they’re eleven, Hazel’s mom is pushing her to make some female friends, and Jack is more interested in hanging out with his male friends than with Hazel. Then the impossible happens: Jack is taken away by a mysterious witch, and Hazel is the only one who can rescue him. Anne Ursu’s Breadcrumbs is a retelling of the fairy tale “The Snow Queen,” and it’s fantastic.
