ePub isn't an Apple format? — it's a cross-platform ebook publishing industry standard, originally in competition with and now adopted by Amazon's Kindle. Ebook reading software for literally any platform should support it.
I should also point out that I am willing to meet people halfway on formats, but I'm not prepared to waste effort on a PDF for you that might just be unreadable — and you haven't told me anything about the screen you want to read it on.
