In a plot which seems to closely resemble the sisters' real lives, Dollhouse tells the tale of three sisters Kamille, Kassidy, and Kyle Rameros who live in Los Angeles.
Their mother has remarried and their new stepfather, a world-famous all-star baseball player, has come complete with two stepsiblings.
Khloe and Kourtney recently explained why Kim isn't taking part in the book's promotion.
'She loves her fans so much, as we all do, and it was really hard for her to take some time off because she doesn’t want to disappoint any of her fans but it’s definitely something that she needs to do,' Khloe recently told Celebuzz.
