I surprisingly really enjoyed this book, which is a genuine shock because I was fully expecting this to be a 2-3 star read! I think what I enjoyed the most was the premise. Mirren is given an impossible task by her beloved dying great-aunt: find a cherished book from her childhood that no one but her has ever seen. While it's a task I would never undertake personally, I loved reading about Mirren's chaotic adventure into the most wondrous places in England and Scotland to find this treasure. 

I wasn't a fan of the romantic plot, to be honest. I found the banter between Theo and Mirren really cringey. I'm also not a fan of the whole "I have a secret I'm keeping from her" plot line and I just know that if this were a full length novel, that miscommunication would've been dragged on for hundreds of pages. I'm glad I was spared that in this novel! I appreciated that he understood sleeping with Mirren would've been a disgusting and deceitful thing to do considering the circumstances. The sole point in Theo's favor! 

The ending made me tear up a bit; it was a wonderful conclusion to the story. My ONLY gripe about said conclusion

is that I do not believe Mirren should've been allowed to keep the book. It was borrowed indefinitely (a nicer way of saying stolen) from the rightful owners, who are still alive by the way, and it should return to them! I think Mirren is no different from those awful booksellers if she keeps the book from June. It's clear that in her old age she can't be trusted to make decisions on her behalf, nevertheless giving away a priceless treasure such as that book. I would've liked to see that book returned to June so her daughters can decide what to do with it.
