It's still there.
It's still okay.
*takes deep, calming breath*
I have now backed up the chapters to my secondary drive and saved them to diskette as well. Tomorrow I'll make a third backup copy just in case.
I can't believe I haven't been doing this all along. Did I learn nothing from the tragedy that befell Ben Aaronovitch? Or lizbee, for that matter.
So very grateful the book is still there. Now maybe I can sleep.
