From Goodreads:

A Happy Hubby?
Hardly! How could John Eames have thought he could spend the rest of his life with a man whose idea of fun is a mid-sumer tour of Civil War battlefields? It isn't that John doesn't love dependable, intellectual Harrison. But there are definitely other fish in the sea, and lately, they seem to be swarming around John!

A Hot New Hubby?
Thanks to a trial separation, John is free at last to embrace his inner Boy Toy. From his San Francisco gym to the beaches of an all-male resort suitably called Babylon, he explores the dizzying array of options available to one who possesses perfect pecs and great hair. There's only one rule in this brash new world where anything goes: every man for himself.
