Shirley Hughes is best known for her Alfie books for toddlers but she recently wrote a book for older children which is well worth reading.
Hero on a Bicycle is set in Italy during World War II and features a Catholic Anglo-Italian family who are, rather unwillingly, drawn into helping the resistance. I won't give away too much of the plot but if you want to read another review from a Catholic perspective that tells you more, click here.
Unlike Hilda van Stockum's The Winged Watchman, this is not a book that is suffused with Catholicism - it seems to be Catholicism from an outsider's perspective - but it is a book which takes the Faith seriously and respects it.
I shall be recommending this book in conjunction with Road to Valor, about another Italian Catholic hero on a bicycle.
