Two Tribes by Fearne Hill

It’s 1995, and troubled seventeen-year-old Matt Leeson harbours three passions: indie music, wartime history, and the posh boy he sits next to in maths class.Not in that order. One of those passions is closely guarded, along with a few other secrets Matt tucks away. Such as his abusive father, the cramped run-down flat he calls home, and the futility of his dreams to escape both.
Twenty-five years later, and plodding Dr Alex Valentine, recently divorced, is looking back on a life less lived. On his failed marriage and the dull bore he’s become, on the empty, lonely weekends stretching ahead. And, in a corner of his mind, wondering what could have been, if only a slender, raven-haired young man hadn’t so abruptly vanished all those years ago.
First love. Teenage love. It should be nothing more than an opening chapter, right? A short prologue even, before the real test of adulthood begins.
But what if that chapter never closes?
