This omnibus edition contains the trilogy of science-fiction books that introduced the world to Mike Callahan and all of the regulars at Callahan's Place. Callahan's Crosstime Saloon is the neighborhood tavern to all of time and space, where the regulars are anything but. These time travelers, talking dogs, alcoholic vampires, and cybernetic aliens really, truly care about each other. Time Travelers Strictly Cash is the policy. Lay your money on the bar and after drinking, make a toast and throw the glass into the fireplace. It's an odd tradition, but one that's led to some interesting stories. Callahan's Secret may be one that nobody would guess, or it may be as simple as listening to all those post-toast stories. After all, shared pain is lessened and shared joy is increased-a concept that could, after a few drinks, lead to saving the world.
