Twice Removed From Yesterday — K.C. Kendricks

Chandler Beck is at a crossroads. To move forward, he has to take a trip back to the biggest regret in his life. He discovers a man happily settled down with a partner, both of whom are ready to call him a friend. When they offer him a place to rest, Chandler ends up in their guest room and with a job at the best restaurant in town.
Once a rising star on the pro golf circuit, a back injury forced August Howard to give up the game. Swallowing his pride, he accepted a job waiting tables and worked his way up to the manager of The Wharf, the area's premier restaurant. He's not happy when the owner does a favor for a friend and hires the seemingly inexperienced Chandler Beck as a bartender.
It doesn't take Chandler long to win over the prickly August, but August is a man with secrets. Their friendship heats up and when August's past comes calling, Chandler pays the price. The only option open is for August to confess all and hope those around him, especially Chandler, will accept he's a different man from who he was in his yesterdays.
