Ilia Tversky has written a terrific children' book. This story is full of comparisons, surprises, interesting events, and funny anecdotes. The way the book has presented the various characters and their worlds makes the story incredibly engaging. It's about David, who lives in a small village in Friendlandia. One day he comes across unfamiliar creatures, two Chuk-buruks, Good and Capricious. They join David's family and become his new friends. They go out, have fun, and share their everyday routines, but Capricious is always unhappy and makes things unpleasant for everyone. The Chuk-buruks and David enjoy exploring the surrounding world and its inhabitants and making new friends. One day, while traveling to a friend's house, Capricious gets lost. David and his friends spend a long time looking for him, and in the process, they discover several strange worlds inhabited by folks with differing personalities. However, they have planned wisely to go through this under varying circumstances. Well, will they find their capricious friend?
