Amy Carter is missing. And there's no one less capable of finding her than Max Bravo.

Max Bravo is a mid-rung opera singer with a diva's towering ego. And he doesn?t do favors. Not until the day he visits a troubled friend in Berkeley and offers to walk her dog.

Max quickly discovers the local dog park. It's an odd, private little world?a preserve for neighborhood crackpots and lay-abouts, and, incidentally, their dogs.

But, the park regulars are friendly. Clubby. They even serve beer. Before long, Max can?t stay away.

When one of the regulars disappears, Max's interest in the dog park turns to obsession. Amy Carter ? beautiful, adored, pregnant ? has vanished. The circumstances bode the worst.

What happened to Amy? The dog park club has brewed up a theory. And they mean to prove it.
