Rosie by Alan Titchmarsh: Rosie Robertson, a vivacious, 87 year old grandma, believes she is heir to the Romanov throne of Russia. She is also a handful for her watchful grandson Nick.
This is a tender story of the love of two people on opposite ends of the age spectrum. When she needs him the most, Nick is there to take in Rosie. She is full of advice, and also pulls some embarassing stunts, yet there is no doubt that she loves her grandson dearly.
There is no generation gap here. Just a wonderful blend of romance and humor and endearing love.
I would put Rosie on your must-read list!
