The Heart Wants - Krystina Rivers

Sydney meets Reagan in an Italian café when Reagan helps her order. Instant best friends, they spend an idyllic fall sightseeing until Sydney's semester abroad comes to an end and she returns to the States. Reagan's a young Army second lieutenant living under Don't Ask, Don't Tell and must stay behind and complete her assignment. But their final night together-complete with a first kiss-lives on in Sydney's mind.

Over the next fifteen years, Reagan and Sydney ricochet in and out of each other's lives, with each parting leaving deeper longings and scars than the last. When DADT is repealed and they both end up in Washington, DC, it's a chance for Reagan to finally win the heart of the woman she has always loved, if only the Army didn't threaten to send them to opposite sides of the world once again.

An epic love story that traverses the complexities of duty, loyalty, and sacrifice across the decades, Sydney and Reagan know what their hearts want, but love keeps slipping through their fingers.
