Colin and Martin's London Christmas (Colin and Martin #2)
Drew Hunt

Colin left the garden gate open and Toby, Martin's guide dog, got out, only to be run over and killed. Although he tries not to blame Colin, Martin finds it hard to forgive his boyfriend.
In an effort to save their relationship, Colin takes Martin to London to spend the holiday with the Rodgers family. There they meet Colin's Uncle Matt, visiting from Australia.
Will the spirit of Christmas, the warmth of family, and the thrills of the big city be enough to mend Colin and Martin's relationship?
