For beginners, 'The Chronicles of Narnia' is a great start. It has simple yet engaging stories and is easy to understand. Another good option is 'Alice's Adventures in Wonderland' which is full of whimsy and strange adventures. 'The Hobbit' is also suitable as it has a relatively straightforward plot and introduces readers to the fantasy world of Middle - earth.
If you're a beginner, 'Stardust' by Neil Gaiman is a wonderful fantasy English fiction novel. It has a charming story about a young man's journey in a magical land. 'Howl's Moving Castle' by Diana Wynne Jones is also a great pick. The story is engaging and the world - building is creative. 'The Sword in the Stone' by T.H. White is a good starting point too. It has elements of Arthurian legend in a light - hearted and accessible way.
