I was hoping to find some online lessons or a workbook, something that doesn't involve sitting in front of a stranger who knows this really embarrassing thing about her. (Obviously, it wasn't her fault, but still.)
Most of the cool stuff is really geared towards kids, which can be fun if she’s got that kind set, or horribly demoralizing and insulting, if she doesn’t. It’s also largely free, so I’d bet if she did tend towards that stuff, she’d already have done it.
The stuff geared towards adults is very one size fits all clunky & fairly pedantic/boring. (Boredom is my enemy).
So one of the benefits of finding a tutor is that they can work with her passions; cooking to car repair, fashion to forensic crime scenes, sex to sailing... whatever it is that she really
digs and use that as a platform to get literate inside.
IF this is something you might do... check out Speech Pathology grad students / put a want ad in their building/website. It’s a doctoral program, so they’re all mostly broke / eager to take side jobs that they can use in their CV / are related to their field, and the treatment methodologies used in Speech Pathology are super relative to building a person up. (SP peeps do CBT and a metric shit ton of other cool things, because they’re often working with neurology patients &/or adults who have suffered from head trauma and are having to relearn skills, including emotional monitoring and regulation, conceptualisations of self, graduated levels of reaponsibility, occupational therapy, tons of neat stuff). Literacy isn’t exactly in their degree path, but there will probably be at least a few students who are passionate about it. Almost always are in psych and neurology majors. There’s almost always at least a couple volunteering at the library, writing lab, taking on clients.
