Parents need never worry about steaminess when reading a Narnia book, and Prince Caspian is no exception. The children, critters, and mythical creatures are way too busy adventuring to give much thought to star-crossed romances. Even kissing and longing stares are absent from the proceedings. Seriously, the land of Narnia makes Hogwarts look like a house of ill repute.
So while we adults might wonder how Narnia remains populated after all these centuries, we can be certain that Prince Caspian will not lead to any awkward conversations about bedroom activities.
