Oxford illustrator Shirin Adl, who grew up in Iran, has collaborated with Muslim convert Na’ima Robert to produce Ramadan Moon (Frances Lincoln, £11.99) a lyrical picture book which captures the spirit of the festival for young children.

The story follows the waxing of the moon from the first new crescent to full moon for 30 days, culmlinating in the festival of Eid, which this year falls on September 20. Shirin, who studied at Loughborough College and won the Hallmark M&S Talented Designer Award, also designs greeting cards.
