Hello there,

Check the "My Reads" or "Library" section in your e-book app or website. If the book is not opening, try refreshing the app or logging out and back in. If it's a PDF or EPUB file, use a reader like Adobe Acrobat, Kindle, or Google Play Books to open it.

I hope this answer helps you. If you have more queries, then feel free to share your questions with us, we will be happy to assist you.

Thank you and wishing you all the best for your bright future.
