I just discovered Literata Book on fontsquirrel:
https://www.fontsquirrel.com/fonts/literata-book
I'm using the ttf that results from running it through the
Kobify Fonts script. It looks like this version of Literata has had the line height adjusted. With Literata I was using a line spacing setting of 0.9. With Literata Book this is equivalent to a 1.1. Some strangeness with letter alignment of bold fonts seems to have been fixed too.
