The Mouse House of Sam and Julia Book

Sam and Julia live in the Mouse House. This is the whole world for them. Julia lives on the seventh floor in the back of the building. They have a tiny room there with their mother. Julia has no father, no brothers, no sisters, no grandparents. Julia is terribly interesting and extremely stubborn. She does not like monotony. As soon as she gets bored, she goes in search of adventure. Together with his friend Sam.
Sam lives in the front part of the Mouse House with his mom, dad, brothers and sisters. He also has two grandfathers and two grandmothers, several aunts and one uncle. Sam is terribly shy and extremely obedient. But when he is with Julia, he is ready for such feats that he would never dare to do on his own. What Sam has too much, Julia has not enough - and vice versa. They are best friends and do everything together.
