Betsy and Tacy Go Over the Big Hill is the third in Maud Hart Lovelace’s Betsy-Tacy series. The girls are now 10 years old and the largely standalone chapters of the first two books smoothly transition into larger story arcs involving a terrible fight with their older sisters and various encounters with the immigrants in the nearby New Syria community. The depiction of their cross-cultural encounters with the neighbouring Lebanese community are gently done, as is the fight with Julia and Katie and its various consequences.
