The 'Merdeka' eBook is exclusive to Kindle. It can be read through the Kindle App on all android devices. If you also have a Kindle device, your place in the book can be synced so that whichever device you open, you can start reading where you left off. Isn't technology wonderful!
The Kindle App is also available for other devices. For more see 'How to get the Book'. The Amazon store links have just been updated.
