there’s a fantastic series of books called The Tapestry – The Hound of Rowan, The Second Siege, The Fiend and the Forge, The Maelstrom (the last book is coming out in October).
To clarify the issue, if the author is deliberately putting his kfira beliefs into his stories, they should not be read (think Phillip Pullman). However, reading stories that reference other religions, pagan or monotheistic is fine, as long as the reader is aware it’s just a story (although you should be careful with pagan religions that are made up). For instance, the Roman Mysteries series is set in Rome, which was a pagan culture – but that has nothing to do with the plotline.
