Budding archaeologist, Jodie wants to share her interest with her cousin Zach.  She wants to take him to Hezekiah’s Tunnel.  When Hezekiah was King of Jerusalem, he had a tunnel built as an escape route in case of attack.  Jodie’s dad challenges them to find the riddle in the middle.  As she and Zach walk the cold, wet tunnel, Zach imagines all sorts of scary things as Jodie calmly explains away all his worries.  They do discover the riddle, Jodie relates much of Jerusalem’s history, and they find an ancient coin.  Ksenia Topaz’s watercolor and pencil illustrations convey present and past Jerusalem.  The story is more about the history of the old city than it is of Passover and could be enjoyed any time of year.
