The best reading experience is for you to switch to a better firmware. We tested against:

• CrossInk v.1.3 or greater
• CrossPoint Reader v1.4RC or greater

Later revisions improve the reading experience. Still, both need some fonts loaded onto them. These are in CrossPoint format! They're generated from fonts you can find off of Google Fonts. Download them below:

EB Garamond (used in the print versions)	Lexend (better readability)
Attach:EB_Garamond-Fallback.zip	Attach:Lexend-Fallback.zip

6. If the browser asked if you want to do this, select yes or upload.
7. Click "Upload" on the page

    1. Exit File Transfer
    2. Navigate to Settings, then Reader, then Font Family
    3. Select the font you want.
    4. Exit back out to the front page
    5. Enjoy reading your books!

There seems to be some extra spacing between paragraphs, and it's increasing...

Download a fresh copy of the ePub. It's the book and the reader's interaction with some bad formatting. I fixed the formatting but the revisions may not have come out.

CrossInk is working on a "fix" for such quirky ePubs.

Generic questions

I'm missing some characters around text in TTLS

This novel uses several unusual Unicode characters that aren't found in many fonts. If you have an eReader mentioned below, follow those instructions first.

That said, you may need to install all of these font families on your device as a fall back font.

• Noto Sans Symbol
• Noto Sans Symbol 2
• Noto Sans Math
