Previous book "The Christmas Book Hunt".
A year has passed since the search for the book "A Child's Garden of Verses", for her great-aunt Violet, and Mirren Sutherland, a book obsessive, working as a quantity surveyor, not only finds her life dull but has a broken heart.
Theo Palliser, devastating handsome, ghosted her!
The book was donated by June, the rightful owner, to the British Museum and she often goes there on her lunch hour to watch people be amazed by it.
And one day she meets Jamie McKinnon who's asking about the "find" person on the plaque and Mirren introduces herself.
He gives her a card with just a name and phone number, and that he has a job for her if she's interested.
Phoning him, he says he wanted a book found, that it was in his house, but didn't know what it was called!
He talks to her boss for a surveyor job, sends her a train ticket to Scotland, for a week before Christmas.
At the station a kid in a bike stole her phone, all her life was in there, and also the ticket, and there's no other place vacant in the train!
But she is wrong because she is taken to an amazing red carriage before the engine.
The MacKinnon Carriage!
It has everything: a bar, a fire, a butler, rooms, books in careful bookshelves and Theo Palliser seated in an armchair!
They arrive a their destination without her killing him and are picked up by Jamie at the terminal, in the middle of nowhere.
And then she understands why he said he didn't know where the book was.
The house is actually a huge castle, Forres, and his grandfather was a hoarder of books.
He can't sell it, build a better road, it's not safe for an hotel, has lots of debts and the Council taxes to pay.
From afar the castle looks magnificent, but close to it is falling apart, and he's the laird.
The only clue his grandfather left him is a piece of paper with a poem!
Mirren had wanted an adventure and there she was in a crazy old castle in The Highlands.
The views are stunningly beautiful but it's so cold, the kitchen and a small living room the only places that are hot.
Bonnie, the only and last member of the staff, takes care of the food, the fire places, and everything they might need.
Jamie, Mirren, Theo and then also Esme, Jamie's sister, start going through the books in the corridors, libraries, everywhere.
A treasure hunt based on a poem!
And to turn it more difficult they are snowed in by a storm, no phone sign, no electricity.
But Bonnie's food is so good.
The first clue found is in a thick book with a swan origami in it and it's all numbers.
Using the Directory of the land line Mirren is able to call the nurse home where her mother works and the recepcionist, who used to be a librarian, tells them the easy way to find a book is the ISBN number.
And they find the name of the book.
But this clue leads to another clue, which leads to another one, and to excursions out of the castle, to a maze, to a fire, to almost dying, to a past love story, to family secrets, to Theo being forgotten by Mirren, to a future love story!
This book is written like a gripping, addictive thriller, with lots of twists.
With lovable and relatable characters.
