I read half of the book from Kristy's Big Day by Gale Gulligan and Ann M, Martins.
So far Kristy's mum is getting married to someone else and they are trying to sell their house before the wedding, someone wanted to buy the house but they can't sell it yet because they have nowhere to stay.
I think that they should try to sell the house to someone else or tell them that they can't move houses yet.
