A self-pub­lished, sim­ple sto­ry of a rabbi’s warm rela­tion­ship with a mouse, to whom he gives the name Mazel, and the haven he arranges for Mazel in his study over the win­ter. The plan is that the rab­bi will allow the mouse to stay and keep warm in the syn­a­gogue, while the mouse will be respon­si­ble for clean­ing up (munch­ing on) the mess the plump rab­bi makes when he snacks in the study. As time pass­es, the rab­bi intro­duces the mouse to Jew­ish cus­toms, Shab­bat, and hol­i­days. The read­er learns about Jew­ish tra­di­tions along with Mazel, in a pleas­ant way. Sen­si­tive warm feel­ings per­me­ate the sto­ry, although there is very lit­tle action and too many words for the tar­get audi­ence. A glos­sary of Hebrew and Yid­dish terms used through­out pre­cedes the text. The soft pas­tel illus­tra­tions ampli­fy the warmth of the unde­mand­ing plot. The book includes a CD drama­ti­za­tion of the sto­ry, accom­pa­nied by hol­i­day songs. For ages 4 – 8.
