Thirty Days, Vol 2 by Belle Brooks

“Life is not always as it seems, Abigail, it can be masked by many disguises.”
Memories are defined as the faculty by which the mind stores and remembers information.

What would you do if you learned your memories were incorrect? That they’d been hidden to hide a bitter truth? Is this even possible?
Abigail McMillian now knows it is, after a life she chose to forget—a life she chose to change—comes flooding back. Suffering from retrograde amnesia triggered by a fall, Abigail must try to piece together her real memories from the ones she fictionally created.
Face to face with Marcus again, the love of her life and the man she’s forgotten for seven years, Abigail’s left with one decision to make: remember the pain she chose to erase, or remain forever blissful, fictitious in a world of her own creation.

That’s unless all is not what it seems.
