hi Jenefer.

but see if this link points you where you need to go.
How do cancel book order Google Search
To cancel an item or an entire order:

1. Go to Your Orders.
2. Click Cancel Items. Note: ...
3. Select the check box next to each item you wish to remove from the order. If you want to cancel the entire order, select all of the items.
4. Click Cancel checked items when finished.

I have cancelled many things on Amazon, but not a digital order. You should be able to go into your Amazon account and cancel that order. I don't know how they would even process a kindle book if you don't have a device.

You should contact whichever store you ordered it from.

fixya doesnt sell products --need to notify seller to cancel order
