While having fun, a valuable lesson is learned in the second book of the "Crystal City" series. Carmella and Sam, both six years old, and Max who is 4 years old, are best friends who just happen to be cousins. With the help of an unlikely friend who can fly, they go up above the clouds to a city made of crystals. Once there, they are met by a wise and beautiful lady who appears to be surrounded by white light. She takes them to a room with a puppy on the door. Once inside, the children find the room filled with a variety of baby animals. The cousins have lots of fun playing with the animals. When the children are ready to leave, the beautiful lady gives them love and imparts a bit of wisdom about the lesson the children learned in the "Baby Animal Room".
