I am in the process of making a book thru Photos. All the pictures have been laid out and am just doing finishing touches. I paused to do something and suddenly I could not retrieve the project. I still see it as part of the list of projects but it would not launch or show the pictures in it. I did not delete it at all. I can see all my photos and albums but not the project. Please help. Thanks

First repair the library according to the instructions in this Apple document: Repair Your Library.
Note: If you use iCloud Photo Library with Photos, this action will cause Photos to upload all your pictures again (from Fix missing or incorrect thumbnails in Photos - Apple Support).
Next, if necessary, restore your latest backup copy of the library made just previous to this occurring and see if the book is in the library and workable. You can restore the library to another location so you don't overwrite your current library. Or rename your current library so the restore doesn't overwrite it.
I tried this but the whole project is gone. The source album for it however is still there and workable. I was just trying hard not to do everything over ie. put a picture in each page of the book.
Do you have a backup copy of your library created just prior to this occurring?
Try restoring it to a different location that your current working library and see if the book is still there fully or in part.
my Photos book project disappeared
