Looooong! So long. The farts were kept to a minimum, unlike the first book in the series. Nilly and Lisa head from Norway to France. Using their time traveling bathtub they visit Napoleon at Waterloo, Joan of Arc at the stake and bicyclist and spectators at the Tour de France. So, while I was reading his hair-brained, incredibly long story of a time-traveling bathtub, what I found is that we were actually learning. Now... On to clean my palette before starting the third book in the fart powder series.
