The Arrangement. Courtland Chronicles, #4

Most people are lucky to find one love-Eric Courtland found two. He's spent the last decade in and out of a tempestuous relationship with his lover, Nick. But all that is nearly over when his new bride, Allison, discovers that his vows of fidelity came with an exception. Suddenly, Eric is at risk of destroying all he cares about, from his burgeoning political career, to the two loves of his life. Terrified of losing everything, Eric proposes an unconventional solution: a non-traditional arrangement that neither Allison or Nick can refuse.  And despite the betrayal and jealousy that plague the birth of their new relationship, the three begin to discover new ways of achieving harmony and balance-and an intimacy beyond anything they expected.
Even as their secret relationship grows, however, blackmailing political rivals and the pressures of life in the public eye create stresses that threaten to tear the three apart. In the end, Eric must decide what he's willing to sacrifice: the political ambitions he's nurtured all his life, or building a new dream with the only two people he's ever loved.
