The Weight of Forever (Grand Harbor #2)
Randileigh Kennedy

Miles finds Olivia to be daring, loyal, and easy to love - which also makes her hard to leave. As long as he keeps his secrets to himself, perhaps he can stay in Grand Harbor longer than he originally planned. Every new adventure pulls them closer together as they spend their days wrapped up in each other beneath the summer skies. They wonder if it's truly possible to carry on this way forever.
The trouble with adventure, however, is that it's often temporary - especially when your secrets are no longer yours.
