I read on three kindles using Whispersync so I send all my mobi files to the Amazon Cloud. I've just realized that whilst I can use custom fonts on my own books I can't bold any font. The only bold option is Amazon Ember Bold. I even have Chare installed but that is lighter on my own books than it is when reading an Amazon purchased book
Is there anything I can do to enable bolding on fonts when reading my own books?
My own books are mobi files sent to Amazon via Send to Kindle.
