If you haven’t read the books in this series, I strongly advise you to do so. Adventures, battles, a Great Lion named Aslan, who is involved throughout the whole story even though the reader might not be able to see it.
I don’t want to give everything away, but I must say this: The last book of the “chronicles” may seem like all hope is lost, but at the very end: it makes you so happy that you want to cry!
C.S. Lewis is a genius! Everything in the books seems to have a parallel with the Bible somehow, and I really feel like if I say anything more I’ll end up giving something away… So do me a favor: read them!
