After having an amazing time at Agrippa's house when they spent the evening under the supervision of his parents - described in Teamwork, Book Two of George Rosling's series The Four - the children have now got the party bug. In this book of adventures, we will enjoy the children getting involved in the Jewish celebration of 'Purim' where everyone loves to wear a fancy dress and have a great time. They will then join in with Basharat's birthday celebrations with his family at their home, where they will follow in the Muslim tradition as his special guests. Audrey then invites her friends back to her house to celebrate Easter with her and her family where they will join in with the festivities and have lots and lots of fun. Who said children couldn't enjoy themselves when they are with special friends? These Four Friends have become inseparable... Enjoy.
