If the OP found The Secret to be appropriate to her level, which apparently from my research is some sort of religious self-help book for adults, then her English can't be that rudimentary. I'm sure you're better acquainted with what is appropriate for ESL learners, but I think you might be misconstruing the intention and ability of the original poster.
What would you suggest? English translations of Perrault or the Brothers Grimm?
Edit: Good suggestions Kiki, though I think the puns and wordplay in The Importance of Being Earnest might be a bit difficult to catch for a beginner.
