Born under different stars -- Mungo a Protestant and James a Catholic -- they should be sworn enemies if they're to be seen as men at all. And yet against all odds Mungo and James become best friends as they find a sanctuary in the pigeon dovecote that James has built for his prize racing birds. As they fall in love, they dream of escaping the grey city, and Mungo works especially hard to hide his true self from all those around him, especially from his elder brother Hamish, a local gang leader with a brutal reputation to uphold. But the threat of discovery is constant and the punishment unspeakable. When Mungo's mother sends him on a fishing trip to a loch in Western Scotland with two strange men whose drunken banter belies murky pasts, he will need to summon all his inner strength and courage to get back to a place of safety, a place where he and James might still have a future.
