Sea Breeze, book 8 : Hold on TighAbbi Glines2015

Six years ago, Dewayne Falco's life changed. He lost someone he never expected to lose. Resigned to punish himself for something he felt he could have prevented, he goes through life without getting too close to anyone.
What he didn't expect was for the girl across the street to move back home and remind him of what they both lost: Dewayne's younger brother Dustin. However, when a miniature version of Dustin opens the door to greet him, Dewayne realizes he might not have lost everything after all.
Sienna Roy loved Dustin Falco most of her life. He was the boy next door, the high school basketball star and her best friend. But when his life was cut short, she realized he left a part of himself behind.
Now, she's back in Sea Breeze, thankful to have a home for her and Dustin's son, but not sure if she can ever forgive the people across the street who abandoned her when she needed them the most — The Falcos.
Betrayal, lies, and forbidden attraction might end Dewayne and Sienna's story before it's even begun.
