Promises series by Amy Lane [MM]

Keeping Promise Rock #1:

Carrick Francis has spent most of his life jumping into trouble with both feet. The only thing saving him from prison or worse is his absolute devotion to Deacon Winters. Deacon was Crick's sanity and salvation during a miserable, abusive childhood, and Crick would do anything to stay with him forever. So when Deacon's father dies, Crick puts his college plans on hold to help Deacon as Deacon has helped him.
Deacon's greatest wish is to see Crick escape his memories and the town they grew up in so Crick can enjoy a shining future. But after two years of growing feelings and temptation, the painfully shy Deacon finally succumbs to Crick's determined advances and admits he sees himself as part of Crick's life.
It nearly destroys Deacon when he discovers Crick has been waiting for him to push him away, just like Crick's family did in the past. When Crick's knack for volatile decisions lands him far away from home, Deacon is left, shell-shocked and alone, struggling to reforge his heart in a world where love with Crick is a promise, but by no means a certainty.

Making Promises #2:

All Shane Perkins ever wanted to be was a hero. But after a career-shattering decision to go down fighting, Shane comes home from the hospital to four empty walls, a pile of money, and a burning desire for someone to miss him the next time he gets hurt in the line of duty. He ends up an officer in the small town of Levee Oaks, and, addicted to the promise of family, he makes an effort to reconcile with his flighty, troubled sister. Kimmy makes her living as a dancer, and her partner steals Shane's breath at first sight. Mikhail Vasilyovitch Bayul dances like an angel, but his past is less than heavenly. Since he left Russia, he's made only two promises: to stay off the streets and stay clean, and to take his mother someplace beautiful before she dies. Making promises to anybody else is completely out of the question-but then, Mikhail has never met anybody like Shane. Earnest, brave, and self-deprecating, Shane seems to speak Mikhail's language, and no one is more surprised than Mikhail to find that keeping promises is Shane's best talent of all.

Living Promises #3:

Six years ago, Jeff Beachum comforted a frightened teenager outside an HIV treatment clinic, and Collin Waters has remembered his kindness ever since. Now, after six years of crushing on the kind, brown-eyed sweetheart of his dreams, Collin is feeling adult and together enough to make his move. Too bad fate, which has never been kind to Jeff, has something else in mind.
Jeff's life had fallen completely apart before that long-ago day, and it isn't much better now. Jeff has toughened up, become self-reliant, been the funny guy his friends turn to, the one who gives advice and comfort when needed. But every phantom from Jeff's past is about to come out to haunt him, and the family Jeff has staked his future on isn't in such great shape either. Collin is more than a starry-eyed kid, and it's a good thing, because Jeff's going to need all the help he can get. No one knows better than Jeff that life can be too short to turn your back on honest love, and that living happily is the best promise of all

Forever Promised #4:

Crick has been home from Iraq for five years, Jeff and Collin are finally married, and Shane and Mikhail are quietly making lives better for the dispossessed teenagers who come their way. Everything is right in Deacon's world, but nothing ever stays the same.
When Deacon's best friends, Jon and Amy, answer the call of an opportunity in Washington, DC, Deacon figures that’s life. You love people, and they leave you, and you survive. Even Benny, Crick’s little sister, is close to grown and ready to start her own future. But Benny loves Deacon, and she owes him—she may move beyond The Pulpit and Levee Oaks one day, but not without leaving something of herself behind. And so she offers Deacon and Crick an amazing gift… and a terrifying decision.
Benny’s offer forces Deacon and Crick to dredge up every past mistake and offer of redemption. And not just the two of them—everybody is forced to examine the chances they've been given and the promises they've made. In a real family, a child is a promise, and to the men and women of Promise Rock, keeping that promise will change their lives forever.
