This classic picture book shows children that every family looks different and all family groups are equally valid and wonderful regardless of shape and size, colour or gender: love is all they need! 
Based on true events at the Central Park zoo in New York, this is a lovely heart-warming story that subtly advocates adoption and contains important messages of tolerance and acceptance. The story would be a good starting point for a conversation about homosexuality and same-sex families.
Roy and Silo are just like the other penguin couples at the zoo – they bow to each other, walk together and swim together. But Roy and Silo are a little bit different – they’re both boys. Then, one day, when Mr Gramzay the zookeeper finds them trying to hatch a stone, he realises that it may be time for Roy and Silo to become parents for real. He finds an egg that needs to be cared for and puts it in the couple’s nest. Roy and Silo look after it perfectly and their new baby (Tango) hatches. The two fathers and their baby are very popular with zoo visitors.
