A dog tries his best to keep his two co-parenting owners and their happiness afloat in this hilarious and touching sequel to Joint Custody by Lauren Baratz-Logsted and Jackie Logsted.

The Man is happy. The Woman is happy. That means Gatz is happy. He'd like to forget about the trouble he made to get them back together—only slightly ashamed at his antics—and focus on the future. The Woman and New Man are about to get married, after all. But when The Woman loses her job because of some bad press about the two of them, her confidence is broken and she can't help but feel resentful towards New Man when his own career stays intact. Gatz has to give it to him; New Man remains as patient as a saint (of course he does).

The Man is doing better, too, thanks to the New Woman in his life, who just so happens to be a writer as well. But two authors in the same relationship can sometimes be one too many, and they find themselves getting quite competitive with each other. But Gatz has faith in them—The Man did learn from his mistakes, didn't he?

Gatz doesn't know what happened to these two perfectly happy couples, but he knows one thing is for sure: not all families are alike, and happiness can be found in the unlikeliest pockets—just like treats!
