Book excerpt: Never was there a subway car who loved her job more than Jessie. From morning to night she carried all sorts of people all sorts of places—to work and school and World's Fairs, over bridges and through tunnels—sometimes she even took a pigeon along for the ride! But as time passed, sleek new silver cars began to take over the tracks, banishing Jessie to an abandoned lot. What will she do with no passengers to carry? And where will she go now that she's no longer welcome on the tracks? Based on the true story of 1960's-era subway cars that are now being used to create artificial reefs in the Atlantic, this stunningly illustrated second book from Julia Sarcone-Roach is sure to delight scuba diving historians and kids alike.
