My experience is limited to Amazon self-publishing. I haven't used Scrivener, Storyworth or Atticus. Hemingway didn't work for me, but I have a lifetime subscription to ProWritingAid (better value than Grammarly and it is a toss-up which you prefer but a must if you are not using a professional editor/proofreader).

It is possible to create a hardback on Amazon (and make it a paperback and Kindle version). Probably the cheapest option for getting a book in her hands.

It might not look as professional as going to a book printer and having them do it for you. Costs will vary.

I hope that helps.

Kind regards
