The Magician's Nephew by C.S. Lewis
Like Roald Dahl, these are books which are not just for children. The Chronicles of Narnia are beautifully written with the Christian message throughout.
The Magician’s Nephew is the first in the trilogy and is the creation of Narnia. Here is the synopsis from Amazon:
Polly’s hand went out to touch one of the rings. Immediately, without a flash or a noise, she vanished. When horrible Uncle Andrew starts experimenting with magic, Digory and Polly find themselves in another world, and at the beginning of an incredible adventure, as the doorway to the magical land of Narnia opens…This is the first adventure in the exciting Chronicles of Narnia.
It took about half the book to get to Narnia, but honestly, that was not a problem. This gives time for character development, the meeting of the witch and the exploration of other worlds, which I would not have none existed had I not read this one.
My favourite character, like most others, is Aslan the lion. He seems to intimidating but has such a soft heart, what an amazing creature. The description of him is stunning.
As mentioned, the Chronicles of Narnia are based around the Christian story – but do not be put off by this. The Magician’s Nephew replays the Creation Story with Aslan creating Narnia and breathing life into the characters and the Tree of Life and how Diggory was not to eat from it or steal from it.
There is a stark warning at the end to not let our world fall into evil and decline.
I enjoyed this book, and would recommend you read it even if you are an adult. Lewis writes in a fluent and entertaining way, it is easy to follow and very enjoyable.
