I see that Foster is working on a book (yay!) and not sure what the timeline is, but wanted to provide a resource to Foster and team that can be a game changer for getting feedback from beta readers. I have no affiliation with this app but used it for myself and think it’s brilliant. It’s available at HelpThisBook.com. It provides an incredibly efficient method for obtaining and organizing feedback on a manuscript for both readers and the author (dashboard views to see high level reactions to sections within chapters). Can’t recommend this product highly enough!
