56. The Mirror Crack'd from Side to Side by Agatha Christie

I'm struggling to get my daughter to read books.  She is a fast reader and does well in school but just doesn't have the strong desire to read.  For some reason she is fixated on It (the Stephen King book) which I won't let her read because of the super creepy ending.  I also won't let her watch the recent two-part movie because it is absolute dogshit and would ruin all that is good about the book.  I gave her Salem's Lot which I later realized is one of King's most boring books.  She read that but it did not ignite a Stephen King fire in here.  I got her Firestarter which hasn't started.  I know for some reason Agatha Christie is trendy among younger readers so I got her a couple of what I thought were classics.  She started this one and just couldn't keep going.  I took it and read it and can see why.

What is quite good about The Mirror Crack'd is the portrayal of the older English village and the development of the modern estates next door to it.  What's not so good is the mystery itself.  I can see how a 13-year old would not find this all very engaging, especially one who has no real exposure to the subtleties of British social culture.  I was a bit disappointed myself in this one.  The set up is good.  A fading and neurotic British movie actress has moved in with her wealthy producer husband to the old aristocratic mansion of St. Mary Mead.  At a reception in her new home, one of her guests is poisoned and it becomes clear that the poison was meant for the actress.  The more exciting storyline honestly is if Miss Marple can get out from under the thumb of her well-meaning but way too keen and strict caregiver (Miss Marple is quite old at this point).  The mystery itself heads off into a couple of dead ends and the resolution, while clever, is not that satisfying.

Anybody know what are the really good Christie's that will get a 13-year old hooked?  Or any other books.  She is deadset against fantasy and especially all these fantasy series that are popular these days.
