Generally, the Irish are more renowned for their love of things green and Guinnessy rather than their work ethic. Strike children's writer Malachy Doyle from this sweeping generalisation; first published at 44, it took Doyle just seven years to surpass his age with titles published (that's 52 books for the mathematically disinclined).
When A Zeeder Met A Xyder continues Doyle's penchant for rhyming books aimed at the younger end of the picture book market. He has quite a talent for it; the rhythm bounces around nicely without becoming confusing, but also without settling into a bland ABAB. The simple language would also let young readers try reading Zeeder alone.
As for story, the lonely Xyderzee and aquatic Zeederzoo are both searching for a friend. Eventually, they team up in their hunt, without realising that by the end of the story, they will of course find that friendship in each other. Nice themes, with a wistful longing for interracial/ cultural harmony that the world seems to lack. The adventurous pair ends up with 37 little Xyderzeeders, so a few 4am feeds in store for them.
Joel Steward's illustrations are suitable but not outstanding. Children may admire the simplicity.
