In Five Years written by Rebecca Serle
You wake up from a nights sleep the day after accepting your boyfriend's marriage proposal, nailing your dream job interview, and realizing that life plan you made is fully falling into place...to being in a strange apartment, wearing a completely different engagement ring and laying next to a different man.
Type A lawyer Dannie, goes to bed just like any other night after experiencing one of the best days of her life, just to wake up the next day...but 5 years in the future. I don't want to spoil it for you, so I'll give you the vague version of the rest. Dannie is severely confused (as anyone who woke up five years later would be), and experiences an intense hour of her future life. She then goes to bed and wakes back up in her regular realm, only to meet the mystery man 4.5 years later and you'll have to read to find out what happens because if I keep going I'll ruin it.
