Joel Silver (YoYo) loves to be a comedian and to play practical jokes. However, when he, his twin sister Ellie (YaYa) and the rest of their fifth-grade Hebrew school class find something surprising in the synagogue's sukkah just before the holiday of Sukkot, it's no laughing matter. Where did the mysterious four-legged visitor come from? What will become of it? Their unexpected adventure brings Joel and Ellie face to face with the importance of shelter and caring for those in need. This sec­ond book in the YaYa and YoYo series focus­es on the hol­i­day of Sukkot. The Sil­ver twins pre­pare for the hol­i­day with their fam­i­ly and their Hebrew school class, cel­e­brate their birth­days, adopt a lost pup­py, play pranks on each oth­er and have an all around good time. Along the way, they learn and grow, teach­ing their non-Jew­ish and less obser­vant Jew­ish friends about Sukkot and about Jew­ish obser­vance, in general. This is a light­heart­ed romp for mid­dle read­ers with some sub­stan­tial mes­sages sub­tly worked into the fun. There are no heavy dilem­mas resolved here but there are plen­ty of sol­id Jew­ish val­ues addressed through­out. Rec­om­mend­ed for ages 8 - 12. Michal Hoschan­der Malen Jewish Book Council Presented seamlessly within the story, Weinstein includes lots of information about the customs of Sukkot. Practical joker Joel and more serious Ellie are believable, likeable characters. Fans of Sliding into the New Year and readers just making the acquaintance of the Silver family will enjoy this peek into one family's unusual Sukkot. Highly recommended.
