38. Half Magic by Edward Eager

Jane is the oldest and Mark is the only boy. Next comes Katharine.  Martha is the youngest and very difficult.  Their mother works all day and they are spedning the summer being watched by Miss Bick, who is a bit sour.  It seems like they are facing a long, boring summer until Jane finds a nickel and puts it in her pocket.  She wishes there were a fire to liven things up and suddenly fire engines are racing down the street to put out a snalll fire on the next block.  The children figure out that the nickel is magic but only grants half the wish.  They take turns making wishes but make sure they wish for twice what they want.  Of course, sometimes they forget the formula and chaos ensues.  It all makes up for a fun, humorous read and a great book for kids.  Rating:  3.75
