“The Rosie Effect” by Graeme Simsion - Change of Rules

In his previous novel, The Rosie Project , Graeme Simsion introduced us to Don and Rosie and the hilariously charming adventures that finally brought them together. Needless to say, there are two stages in the lives of such couples: before and after marriage. Now that they are living together as husband and wife, in a different city, with different jobs, things have started to take on a different meaning... especially when Don learns that Rosie is pregnant.
